When I get upstairs Sue isn’t in, but Ted is pacing the floor and Ellie is sitting staring up at him, all wide cow eyes, hugging her knees, and Jack is standing over his desk, fiddling with his camera. Nobody has thought to turn on the overhead light and the effect is dark and murky.

‘What’s going on?’ I say, putting my coffee on my desk and shrugging off my coat. I hang it on the back of my chair and throw the umbrella onto the floor. The sky outside darkens and thunder growls.

‘There you are!’ Ted whips around to stare at me. He’s got that look in his eye again: excitement and fire. I glance across at Jack who rolls his eyes. ‘Our boy Jack here has given us a great tip-off from his copper boyfriend.’ He taps the side of his nose. ‘Although, obviously, we can’t reveal the source if anybody asks.’

I pause, surprised. Finn said he never gives tip-offs – and I know Jack has asked many times.

‘A body has been found.’

Nothing new, I want to say, but I don’t. Margot asked me not to tell anyone and I’ll respect her wishes and do the right thing, for once.

I pretend to look shocked.

‘The police think it’s Flora Powell,’ he says. ‘You know, the sister of Heather Underwood.’

‘Yes. I know who Flora is.’

‘But that’s not all,’ he says. He can hardly contain himself. He’s like a comedian on a stage who can’t wait to deliver the punchline. ‘The body has been found in a house in Southville, Bristol.’

I frown. Southville? My stomach twists. Please no …

‘In a Victorian house in Ridings Road, apparently owned by Clive Wilson.’

I feel sick. ‘What?’

His eyes are shining. ‘That’s right. At last there’s a motive. It seems like Clive Wilson killed Heather’s sister. She must have found out somehow, and shot him in revenge.’

My head is spinning. It would make more sense than the idea that Heather had shot the Wilsons in some indiscriminate attack. Heather was always ultra-protective of her sister.

‘Can you and Jack go to the address now? See what you can find out?’ It’s not really a question and Ted has already turned away to talk to Ellie before I can answer.

Jack pulls his camera case onto his shoulder. Without speaking, we leave the office, almost bumping into Sue as she’s coming through the front door. She knocks me with her elbow and my coffee spurts over the top of the plastic rim. She’s wearing new glasses that take up almost half of her face.

‘Where are you off to in such a hurry?’ She laughs, pushing her glasses further up her nose while I lick the coffee from the lid.
