It was a four-hour carriage ride from Wapping to the village of Seal, just outside Sevenoaks in Kent. This considerable ride was made worse by the persistent presence of Edward Markland, who spent his time saying very little but exuding a smug sense of superiority. It made for a tiresome journey, and Horton found himself staring at Markland on occasion and thinking to himself of what Sir Joseph had said to him last night.
Detective Horton. It has a ring to it, does it not?
Sir Joseph’s stories of ancient seers and hidden texts had been suitably resonant with darkness descending on the river, but did they hold any root in the real world on this lovely spring morning? What did that phrase the real world possibly mean, when set against Sir Joseph’s tales of mysteries and matters celestial? As he ignored Markland, he pondered Sir Joseph’s proposal to send him to St Helena.
It was an extraordinary idea, and Harriott had said nothing of it as the strange little meeting broke up. It had been left to Graham to take Horton aside and talk to him of it, while the other two old men sat silently, not waiting for an answer. It had been more like they were waiting for death.
‘Feel under no compulsion,’ Graham had said, sotto voce and with a conspiratorial hand on Horton’s arm. ‘It is an astonishing thing to ask of you. But also, know this, Horton: your enemies are all around. And soon, all three of us will be gone. And what then?’
Horton pondered that question in the Kent-bound carriage. What had Graham meant, precisely? Who were his enemies? Was Markland one of them? And how did the ancient troika – Harriott, Graham and Sir Joseph – come to be his protectors?
He had not, he believed, deliberately enraged anyone in his years investigating matters for John Harriott. So it bemused him to think he may have made enemies. But then he considered Sir Joseph’s strange tales, and wondered if it might be what he had learned that made him dangerous to certain powerful men. Not what he did or said, but what he had unearthed.
And then there were practical questions. If Harriott were to die soon, who would he work for? He saw no appetite for his unique skills among other magistrates – even Markland might baulk at making him an employee. He could be cast into penury at the quiver of a quill. And what then? A middle-aged mutineer with a single indescribable skill – that of a form of investigation that nobody seemed to know they needed. What possible future awaited him on the other side of Harriott’s death? Did the world need detectives?
Perhaps that had been Graham’s meaning. Perhaps he did not have enemies, quite – what he had was a scarcity of friends. Would there be opportunities in St Helena? Or even further afield? Might he find friends in further-flung corners?
He would have liked to discuss St Helena with Abigail today, during this long ride – but there had been no question of bringing her along on a journey such as this, however hesitant he might have been about leaving her in London. He had left early this morning and had gone to Harriott to propose this trip, and his magistrate had agreed, on one irritating condition: that he inform Edward Markland.
Markland had agreed, with resignation, to Horton’s request. But he had insisted on accompanying him to the country residence of Alderman Robert Burroughs. ‘A Wapping constable does not just show up on the doorstep of one such as Burroughs,’ Markland had said. ‘Is it really necessary to visit him unannounced?’
Horton, and Harriott, believed it was. Markland had been persuaded, and now here he was, glaring at Horton with his remorseless self-obsession, a baleful gadfly with sadly necessary powers.
Turning away from his own future, Horton tried to focus on the immediate questions relating to the immediate matter: why were the Johnsons killed? And, thus, who killed them? There was a form in the deaths, a pattern shared between those of the Johnsons and those of the former assistant treasurers of St Helena. Each death had told its own little drama; had contained its own staging. A family smashed to bits on the same street as the Marrs, four years before. A captain dead and naked on Boxhill. A captain dead and stabbed in a side alley in Kingston. A captain impaled on his own railings, a whore inside. A captain dead in the river, apparent suicide.
Salter’s story, then, of this strange substance Prussic acid and its hugely poisonous qualities. Its stench hung over these murders, both literally and figuratively.
And then, that story of the strange marking, the one he had seen on the Johnsons, and the one found on the whore. John Dee’s Monad. A direct link between all these deaths, and across the years – and another obscure association with St Helena, via that reference in the essay on John Dee.
Those two dull syllables: John Dee. John Dee. John Dee. Like a heartbeat that would not cease. And four others: St Helena. Again and again and again, that mysterious island rose up before him in this case. It reminded him of another four-syllable island – Otaheite – and the way that place had haunted the eyes of the sailors who had visited it. Paradise had imprinted itself upon their souls.
They pulled into the driveway of Seal Castle, the walls as high and as grand as any Horton had seen. The drive passed through a thick wood, and Horton watched closely for the shape he expected to see somewhere in the shadows. But he saw nothing. If the thing he suspected to be there was to be found, it must be behind the house, or further into the woods.
The house was as vast as Markland had said. Robert Burroughs had earned untold thousands from his gold and silver trading, and that gold and silver had been subject to a reverse alchemy, transmuting back into base elements: stone and brick and marble and glass. Seal Castle was gloriously appointed, supremely tasteful, hidden away behind its walls and within its woods. Horton thought of the unimpressive heron of a man who had appeared to them at East India House, and hoped fervently he was not at home.
Markland took a scroll from inside his coat.
‘The warrant,’ he proclaimed, grandly. ‘It is incontestable, but it would be better were it to come from me. Particularly if Mr Burroughs is at home.’ His face was grim and determined, and Horton found an unexpected shard of admiration for this conceited little fellow.
He watched Markland step down from the carriage, and walk up the enormous steps to Seal Castle’s door. He knocked upon it, and a middle-aged fat man dressed in the garb of a butler opened it. Markland spoke to him, and was shown inside.
Such a house, Horton thought. One could fit the whole of Wapping inside its gardens, and Shadwell and Ratcliffe too. He found himself to be almost afraid of this building, or more precisely of what the house represented: money, power, privilege. It encapsulated all his concerns as to the future. He was afraid. He was afraid of how men who lived in such places might deal with a Nore mutineer and his wife should they lose the protection of an ill and impoverished magistrate.
The door to the house reopened, and Markland reappeared, accompanied by the fat butler. They made their way down the steps to the carriage, and Markland opened the door to speak to Horton.
‘Mr Burroughs is not at home today. He travelled to London this morning.’
Perhaps they passed on the road, thought Horton.
‘I have told this fellow,’ continued Markland, ‘that I am charged with asking him some questions, in the name of Justice. And that I have a warrant to enter this property, and to ask him and the other servants questions.’
The warrant had done its work, then – though Horton believed it would not have guaranteed entry if Robert Burroughs were here. Nonetheless, the butler was acquiescing. Markland’s words must have had some effect.
‘Now, Horton,’ said Markland. ‘Let us go inside, and get this over with.’
‘That won’t be necessary,’ said Horton, and Markland glared at him. ‘Tell me this: does Seal Castle have an ice house?’ he said to the butler.
The butler frowned, and Markland took Horton’s arm and whispered sharply in his ear.
‘Constable, what on earth are you about?’
‘Yes, sir,’ said the butler. ‘We have an icehouse. In the woods behind the house.’
‘We need to see it. Immediately, if you please. And bring a key.’
Burroughs’s icehouse was to the rear of the house. It was of recent construction, its bricks forming a near-perfect red half-sphere embedded deep into sandy soil, the pointing uniform and without cracks. A small door in the side of the sphere was secured by a heavy padlock. The icehouse was in deepest shade, on a north-facing dip beneath a thick canopy of trees, hidden from the sun like a sleeping dragon.
The fat manservant unlocked the padlock, and opened the door. He glanced at Horton, as he had done time and again, and Horton wondered if a note had already been sent into the City to inform Burroughs of the invasion of his property by unexplained investigators. What had Markland said to the servant behind that closed front door, while he waited in the carriage?
Horton was the only one to go inside, carrying an oil lamp supplied by the manservant. Inside the icehouse it was pitch dark, the only natural light coming from the little door, and he could see immediately that he was wrong. This was just an ordinary icehouse. Meat hung down from hooks on the walls, and on the floor of the icehouse were metal boxes containing bottles of liquid drifting in thick dark water. He put a finger into this liquid; it was ice-cold, and there were solid shapes within it where the water had made its mysterious transition into a solid.
A well-appointed, well-kept, well-designed icehouse.
A thought occurred to him, passing his lamp around the cramped interior. This was a rather new icehouse. He went back outside, blinking already, despite passing barely three minutes within.
‘This icehouse was recently built?’
The butler nodded.
‘Yes, sir.’ He had called Horton ‘sir’ since their first arrival, apparently unable to place a London constable within his social taxonomy. ‘At the beginning of the current century.’
‘It replaced another icehouse?’
‘Yes, sir.’
‘Does that icehouse still exist?’
The butler frowned.
‘Well, yes, sir. These things are impossible to demolish adequately, and . . .’
‘Where is the old icehouse?’
The man pointed through the trees.
‘Just up there.’
‘Take us there, if you please.’
The three of them walked down a small defile and further into the woods. It was darker, colder, altogether more forbidding within these trees, and Horton wondered why the new icehouse was not built in here – the conditions were so much more amenable to the creation of frozen water. Perhaps it was as the butler had said: these things were impossible to demolish.
And there it was: squat, black, ugly, old, an excretion from the gloomy hillside, a barren piece of snot on the face of the wood. Bigger than the new icehouse, its door an ancient piece of oak secured with another padlock, this one looking as if it had been placed there by Cromwell himself. But no – on Horton’s inspection, the lock revealed fresh scratches at the point where the key had been inserted, presumably recently, and presumably in fumbling darkness lit only by a torch or a lamp. Horton could see the scene vividly – a carriage waiting on the driveway, men huddled round the door, men going inside to remove the cargo within.
But more than that, the door held a clearer message. Painted on its surface in lime was the image of Dee’s Monad, untidily rendered but entirely deliberate. Beneath the Monad, a single word: Beware.
And hanging in the air, the bitter stench of almonds.
‘The key?’ he said to the butler, knowing the likely answer. The man had no key. He stared at the door in wonder. Horton looked around on the ground, and picked up two heavy rocks.
‘No, sir, you may not . . .’ said the butler, but fell silent when Horton turned to him, a dedicated man armed with heavy stones. Horton looked at Markland, who said nothing but nodded slightly, in a way that might be denied later if it came to it.
‘I would step away, sir,’ Horton told Markland, and the magistrate did as he was told. The butler went with him. They stood some ten feet away.
Horton turned to the lock, and began to smash it between the two stones in his fist. It took a while. Flakes of the rock were sheared away by the impact, and the sound of metal on stone clattered through the trees, but eventually the old lock surrendered its ancient grip, and the door opened.
Immediately, the stench in the air deepened, and it was as if almond-gas filled his nostrils and his mouth. His head was suddenly in sharp pain and then, just as suddenly, his mind deadened and began to switch off, and the observing part of Horton – the part that was always active, always cataloguing and classifying – watched his body shut down, like a ship lowering its sails as the wind drops, and darkness rushed up from his feet, and he fell.
He awoke to light dappling through the carriage window, and the regular rocking of its movement. His head groaned in pain, and his skin felt numb and oddly unnatural, as if another man’s flesh had replaced his own.
He leaned out of the window, and yelled up to the driver to stop. Then he climbed out, slowly, every move slashing pain between his temples.
‘Where are we?’ he asked the driver.
‘Just coming up to Bexley.’
‘How long was I unconscious?’
‘Two hours or more. The magistrate ordered me to get you home and seek out a doctor.’
Two hours! He thought about heading back to that icehouse – but would the driver even take him? He had his orders from a superior.
It is gaseous at 20 degrees Celsius, Salter had said. Which meant the temperature in the icehouse must have climbed sufficiently to turn some of the acid into gas, and for that gas to escape when he’d opened the door. Was that right? Was that how this worked?
Standing outside the Shadwell carriage, there was a quiet moment. He imagined madness was about to descend. It would spread out from Seal Castle, the residence of Mr Robert Burroughs, alderman of the City, gold and silver broker and Proprietor of the East India Company. Less than thirty miles from where he was now standing, the London establishment was carrying on its normal day, unaware of the fuse which had been lit in a Kentish wood.
But what should he do next? He was in Kent, with a carriage driver over whom he had no authority. Behind him, a magistrate he did not trust was responsible for the thing he had uncovered: a secret icehouse, with a now-familiar symbol on its door. He found himself asking an obvious question: why, actually, had Markland come with him at all? And what had Markland been doing in those two hours he had been unconscious?
He did not, he decided, need to travel back to Seal. The presence of the icehouse was enough. It connected Robert Burroughs with the murder of the Johnsons, if what he suspected of the sequence of events turned out to be true. A great anxiety was coming down on him, just as that awful gas had enveloped him, but what was he to do? He needed to get back to Abigail. If he was right, the Company was elbow-deep in all this, and it would stop at nothing to hide its guilt.
He climbed back into the carriage, and they rode back to London. He asked the carriage driver to take him directly to Lower Gun Alley, and the driver agreed. He would check on Abigail and Rat and talk to the other boys, and then walk back to the River Police Office to share his information and his concerns with his own magistrate.
As the carriage turned into Lower Gun Alley, Horton saw a dark shape on the ground, and instantly his acid-dulled senses raced. He yelled at the driver to stop the carriage, and jumped out.
It was Cripps lying there, and he had been knocked senseless. The boy groaned. The instrument of his injury seemed to be a brick lying nearby. Horton looked at it, and then rushed into the building through the ominously open door.
Up the stairs to the first floor, and already he could hear the sound of a woman sobbing, and the flow of air was different through the landing and staircase, suggesting an open door or window. Running inside his front door, he found them in front of the fire.
Abigail was kneeling on the floor, and Rat was lying across her, his head in her lap. They were framed by the fireplace, though no flame crackled behind them. The night was too hot for that. A long dark line lay on the floor. The poker from the fire. Horton went to them, but Abigail looked up at him then.
‘Give him room, husband,’ she said, her sobs stopping while she spoke, her hand still repeatedly stroking the boy’s forehead, which was covered in his dark blood. Abigail’s fingertips were covered in it. ‘For God’s sake, give him room.’
He had never seen her so unhappy, so distraught, so miserable. His heart broke.
‘Bloody . . . ’ell,’ said Rat, his voice barely audible. ‘Bloody . . . ’urts, that does.’ He never looked at Horton. His eyes were fixed on Abigail. ‘Has ’e gone, missus?’
Abigail, unable to speak, nodded.
‘Did ’e ’urt you?’
Rat’s aitches were draining away. Abigail shook her head.
‘Well, then. That’s all right, ain’t it?’
Rat smiled then, and turned his head slightly to where Abigail’s hand cradled his cheek. His dimming eyes looked at Horton.
‘I cut ’im, sir,’ he said, his voice fading like a passing rainstorm. ’’E didn’t get away un’armed. The skinny ape’ll be walkin’ with a limp for some days yet.’
How long had Rat been lying here, fighting death, waiting for Horton to return so he could pass on this message?
The boy looked at Abigail again, then closed his eyes, and smiled.
‘You smell like flowers,’ he said, and died.
