GERTRUD MOLANDER HAD made herself perfectly clear. Under no circumstances did she want to meet or have any form of contact with him. Fabian had no trouble understanding why. He sought her out to ask questions that had shaken her entire existence to the core. She had gone from believing everything was right as rain to being forced to realize just who she was married to.

Now she was home in bed, sick, and he was once again going to jam his foot in the door and barge in against her will. This was his chance – and maybe the last one he was going to get – to make her understand that she was no longer safe in her own home. That she had to get out of there as quickly as possible. So he had ducked out of work an hour earlier than planned.

Ingvar Molander was bound to be using his phone to keep track of where Fabian’s car was, and it had to be assumed he was tracking his mobile as well. Consequently, he’d left the car at home with the phone safe in the glove compartment and arranged for Sonja to drive it down to the ferry for their first trip to see Theodor in Helsingør.

Fabian himself had walked down to Kopparmölle Square, where he’d caught bus number 2, which he’d then disembarked twenty-five minutes later at Ramlösa Brunn. He’d continued across the tracks and past Ramlösa Wok-Express, where just over a week ago he’d run into Gertrud when he was interviewing her neighbour about the murder of his wife, Inga Dahlberg.

It had been the worst possible timing. Gertrud had instantly reacted to the investigation having been reopened and questioned why neither she nor her husband had been told about it. Since then, it had only been a matter of time before Molander caught on to what was happening.

Lindhultsgatan was only a few hundred yards away, and when he rounded the corner he realized he only had twenty minutes before he had to start heading back into town to meet Sonja.

He continued up towards the house and noted that Gertrud’s car and bike were both missing from the driveway. Once he reached the front door, he rang the bell and waited. Maybe she was asleep. He leaned over the porch railing to peer in through the kitchen window. The lights were off inside and everything looked neat and tidy. No food sitting out, no plates or glasses. Nothing. The countertops were so spotlessly clean they’d pass for mirrors.

Gertrud was the epitome of the dedicated housewife, always cleaning. Probably one of the last of her generation. And yet, something about the advertisement-clean kitchen made him feel uneasy. He pulled on his leather gloves and took out the keyring he’d found in Hugo Elvin’s desk drawer.

He’d already found the doors that three of them unlocked, which meant the other four were possible candidates. Two of them were marked with green cloth tape inscribed with handwritten question marks. The other two were marked with white tape; there was a fish on one and a six-digit code – 759583 – on the other, and since a rectangular code lock with two columns of numbers was mounted on the wall next to the door, he started with the latter.

It went in smoothly. At least at first. After a while, it seemed to get stuck, but with some wiggling, it went all the way in. But he couldn’t turn it. He tried both directions, applying as much force as he dared, not wanting to risk having the key break in the lock. The other white key didn’t fit at all, and nor did either of the green ones.

He gave up and instead went around to the back of the house and up onto the wooden deck, past the grill, which, in true Molander style, was meticulously covered up and sitting next to garden chairs that were propped against the table in case of rain.

Nothing had been left to chance. Not even the electric whirring that abruptly started up underneath his feet. He instinctively reached for his gun before realizing it was a robot lawn mower emerging from its bespoke charging alcove under the bottom step of the deck.

He went over to the terrace door and used his hands to block out the light so he could peek inside. The living room looked like it always did. The rug, the furniture and the curtains, all different shades of beige, and on the walls nondescript landscape paintings jostling for space with pictures of birds and dried flowers.

The white key with the six-digit code fitted into this lock, too, but this time he could turn it. After slipping inside, he quietly closed the door behind him and listened for noises. There was only silence.

Gertrud’s collection of owls was set out on a shelf in the display cabinet, just like last time he was there. And in the middle of the crystal parliament, he spotted Elvin’s surveillance owl. In many ways, the location was far too obvious given that the objective was to bug a canny forensic scientist in his own home. But the owl collection was probably so entirely Gertrud’s domain that Molander hadn’t even thought to check it.

He continued towards the bedroom and tapped the closed door gently while pondering what to say. When the only response was more silence, he eventually pushed down the handle and opened the door.

He couldn’t say what he’d expected to find, except possibly Gertrud, asleep. The bed was made and the pillows fluffed like in a hotel room. No clothes on the chair in the corner, no tissues, no glass of water, nor anything else for that matter. And no Gertrud.

In her message, she’d explicitly said she was home in bed. Was she resting somewhere else in the house or was it all just a— Had it actually been Molander texting him back? Had he taken her phone and sat there across the table from him, typing out replies to make sure no one noticed her missing?

The place did look extremely clean.

He went over to what looked like Gertrud’s side of the bed and pulled out the drawers in the nightstand. First the top, then the bottom one. Both were empty. Same thing with the chest of drawers and the two wardrobes on her side of the room. No clothes anywhere. The room smelled of cleaning products and when he dragged a finger across the bottom of the wardrobe he couldn’t see so much as a speck of dust.

Had he cleaned her away? Was that what he was looking at? As though she never existed. But when would he have had the time? Less than two days had passed since their row in the living room, and if Molander was to be believed, he’d spent the entire night in the police lab.

Judging from what he’d heard of their fight, Molander had been caught off guard by the extent of Gertrud’s knowledge, which made it less likely he’d had a plan in place for what to do with her and more likely he’d been forced to improvise.

Fabian went over to the other nightstand. On it lay an old physics textbook he recognized from his school years. A piece of paper stuck out from among the pages. He flipped to the marked page, halfway through the chapter on electrical theory, with page upon page full of flowcharts, equations and all kinds of computations. There were also a few hastily jotted notes in the margin.

Self-ionizing. Conductive. Hydronium: HO– (hydroxide), H3O+ (trihydroxide)

It was definitely Molander’s handwriting.

200l/24h=8.33l/h/60=0.14l/min

But what it meant exactly was less easy to decipher.

Impedance of human body = skin resistance + internal resistance = approx. 1000Ω

Could it have something to do with his plan for Gertrud?

>50mA. X sek

Fabian hurried out of the bedroom and threw open every door he could find. One led to a small storage room crammed full of winter clothes, shoes and cleaning implements, another to a small guest bathroom with an old magnetic soap holder by the basin, a third to a small study cum guest room, complete with bed, desk and desktop computer.

In the basement, he found a boiler room and a utility room with a door leading straight out into the garden. In addition to a washer and dryer, it also contained a sink that was as spotlessly clean as the rest of the house. A pair of thick waders for fly fishing hung on a hook on one of the walls and along another were shelves that housed an impressively large wine collection.

The last door in the basement was made of metal and had neither handle nor keyhole.

‘Hello! Gertrud, are you in there?’ he shouted and banged the door as hard as he could. ‘It’s Fabian!’ He pressed his ear against the cold metal but heard nothing.

Turning around, he discovered a small hole in the wall on his right; when he gingerly inserted a finger, he realized it was a flap that could be opened. Behind it was a keypad with numbers from 0 to 9.

He pulled out the key with the six-digit code and after he punched it in there was a faint rush of air as the metal door slid open, disappearing into the wall. The room behind it was reminiscent of a small museum, full of shelves, display cases and glass counters.

He had seen inside it two years ago. Molander and Gertrud had invited the whole team and their partners to a barbecue, even though they were in the middle of a very demanding investigation. Lilja had taken him down to the basement and the metal door had been open. Inside was everything from handguns to knives and small glass phials full of toxic substances. She’d even shown him a collection of mangled bullets that had killed their victims.

He opened a built-in freezer and found that it was full of plastic containers, small, transparent plastic bags and various other sundries, all labelled with combinations of letters and numbers.

Lilja had told him it was all stuff from closed investigations, and she’d claimed it was the urge to collect, coupled with unadulterated geekiness, that made Molander such a capable forensic scientist. There was probably truth in that, but it also explained why he’d become a serial killer.

It would take him hours to go through it all, and right now his priority was Gertrud. Unfortunately, she wasn’t in the room and, as far as he could tell, there was no trace of her anywhere.

He was too late. He could feel it. The only question was when Molander had found the time to move her from the house. If that was what he’d done.

The garage. Why hadn’t he thought of that?

The thought triggered a flood of images, each more gruesome than the next. Whatever Molander had done to his wife, he’d obviously done it in the garage. That was where his workshop was. That was where he kept his tools, and that was where he could work late into the night without drawing suspicion.

He hurried back out of the room and up the stairs, through the living room towards the terrace door, all the while picturing Molander backing his car just far enough into the garage to load up the black bin bags full of body parts without being seen.

After locking the door behind him, he hurried across the deck and down onto the lawn, where the robot was still attacking the grass. The side door to the garage turned out to be unlocked, and just as he’d suspected, there was a worn workbench with a vice inside. There were also saws, hammers and pliers, all hanging on their designated hooks, and on a shelf he saw a drill next to a circular saw and a few rolls of black bin bags.

But there was no visible blood. Not on the workbench, not on the floor and not on any of the saw blades. Not so much as dry spatter anywhere. What he did see was a crumpled sheet of paper on the workbench, next to a roll of white electrical cord. He went over, smoothed it out and started to read.

Ingvar,

I didnt know where to put this letter to make sure youd find it as quickly as possible. Youve been so busy lately we barely see each other, and the few hours youve been home youve spent either in the basement or out here in your workshop.

Right now, youre probably thinking what a coward I am for not being brave enough to say what I have to say to your face. But the truth is that Im afraid. Yes, Im afraid what you might do to me.

You always had this darkness inside you, a temper whose short fuse has at times had you on the verge of violence. Thats something Ive been well aware of ever since we first met. My father warned me about it and wanted me to leave you. But I dismissed his concerns, and I want you to know that Ive never felt threatened. Not until last Sunday.

You didnt do anything, but you thought about it. I could see it in your eyes, and Ive never been more afraid. You probably think Im exaggerating and being hysterical. Be that as it may, but Ive come to realize it was probably exactly what I needed to finally take this step.

It might come as a surprise to you, but its actually something Ive been thinking about quite a lot over the past few years. But as with the concern my father expressed, I just dismissed it and kept pretending everything was fine. That the constant, nagging worry about who the man Im married to really is was exactly that, exaggerated and hysterical.

But I cant turn a blind eye any more. Despite all the good years weve had together, you and me. Even though youve been the most important man in my life and a part of me still loves you, Ive decided to leave you.

So Im going away for a while. It doesnt matter exactly where to. The important thing is that I need time and space to find my way back to who I am. So please, Ingvar, I beg you. Dont try to find me so you can set me straight.

Believe me. I know what Im doing.

Gertrud
