Katrin had waited up for them.
‘I’m so pleased you’ve decided to stay,’ she said to Juliet. ‘The bed’s already made up. I’ve put a towel and some toiletries on it. Is there anything else you need?’
‘Just a glass of water,’ said Juliet. ‘I can fetch it for myself.’
‘Time we were in bed, too,’ said Katrin after Juliet had left them.
‘Yep, too much for us all to do tomorrow. No point in being knackered as well. You know, when I was dozing in the squad car earlier I almost thought I’d worked it all out. It’s gone again now.’
‘It’ll come back to you,’ said Katrin.
Tim had nodded, but retrieving the idea that had almost surfaced continued to niggle away at him as he lay in bed. It destroyed any prospect of sleep.
He tried to recall the conversation he’d had with Martha Johnson. Suddenly he sat up in bed.
‘That was it!’ he exclaimed.
‘Oh, Tim, for goodness’ sake, what now?’ said Katrin, grumpy at being roused from sleep.
‘Sorry, I didn’t mean to wake you. I was just thinking back to when I spoke to Martha Johnson. She said there was an old cesspit under her office. It slipped my mind because we talked about cesspits every time we went to Silverdale Farm – one of the Fovargue businesses involves emptying them.’
‘I’m sorry, I really don’t see why that’s significant.’
‘She said Fovargue wanted to preserve the cesspit. Josh Marriott was there at the time. He said it ought to be filled in.’
‘I’m still not with you.’
‘We’ll have to uncover that cesspit tomorrow. I think Martha Johnson may have been buried there.’
