‘Jack!’ I gasp, about to tell him everything. It’s been ages since he rang me in the evening and usually only when Finn is working nights.

‘I’ve found out something I think you’ll be interested in,’ he says, his voice serious and very un-Jack-like. We usually have a bit of banter on the phone first.

‘O-kaaay …’

‘I did a bit of digging after you found that card with the flowers.’

‘Flowers?’ I’m still thinking about a possible stalker in the building opposite and have to concentrate on what he’s saying. ‘What flowers?’

‘The ones that were left in Clive Wilson’s garden with the threatening note attached.’

I slump onto my bed. Suddenly I feel exhausted. ‘Right.’

‘I phoned the flower shop – they’re in Bristol – because the name and address was on the card. I remembered it after you let me see it. And –’ he coughs, sounding embarrassed ‘– I pretended to be Finn. Don’t ever tell him – he’d kill me.’

I laugh, mostly with relief that Jack sounds like his old self again. ‘Bloody hell, you’re getting as bad as me. What happened?’

‘I scared them into telling me who purchased the flowers. You’re never going to believe this but … it was Adam.’

‘Adam.’ I sit upright, in shock. ‘Adam Underwood?’

‘Yep.’ He sounds very pleased with himself. ‘Adam asked the woman in the shop to write the note. She didn’t think anything of it – he said it was a joke for a friend’s birthday.’

I’m going to have to tell Margot. ‘Good detective work, DS Jack Renton.’ I laugh.

‘I’m wasted in this job. No need to thank me.’ He’s chuckling when he hangs up.

I try to ring Margot but it goes straight to voicemail so I leave a message. Even though we don’t really text each other – Margot’s always preferred to talk – I tap out a quick text anyway. If she’s speaking to Adam tonight she’ll want to ask him about the note as well. Why did he send it? What’s going on between him and Clive?
