He patted her on the arm. ‘It’s all right, I don’t bite. Would you like a signed book? I’m sure there’s a copy or three knocking about here somewhere.’

‘Eeek. . .’

Logan took out his Grampian Police business card and passed it across the tabletop. ‘Your woman who answers the fan mail, can she forward everything suspicious on to us? ’

‘Don’t know if she keeps it, but we can find out. . .’ He moved the mouse about and clicked on things for a moment, then his fingers rattled across the laptop’s keyboard like machine-gun fire. ‘Done. She’s in Iowa, so it might take a while. I can never remember how many hours they are behind UK time.’

‘But you’ve not noticed anyone hanging around, behaving suspiciously? ’

Hunter raised an eyebrow. ‘The place is full of actors and film people, Inspector. All they do is behave suspiciously.’

It looked as if Anthony Chung’s parents were actually home this time. An ugly Alfa Romeo four-by-four and a silver Porsche sat on the driveway behind the gates, both of them looking brand new, with custom number plates. Hard to believe that only three people lived in a house that big; a football team would have rattled around in it.

PC Sim pulled up at the kerb and peered out through the rain-flecked windscreen. ‘Not short of a bob or two, then. Probably explains why their kid turned out the way he did. Rich and spoiled.’

‘And dead.’ Logan set his phone on silent, climbed out of the car, and hurried up the path to the front door – huddling under the porch as Sim ambled after him, glancing back over her shoulder every couple of steps at the signed limited edition hardback copy of Witchfire on the dashboard.

She straightened her stab-proof vest. Then reached for the doorbell. Ravel’s Bolero kicked in, followed by the bellowing of the massive Alsatian.

There was a buzz, then a woman’s voice crackled from the intercom, mounted beneath a security camera. ‘Who is it? ’ The accent was posh and English. One of those BBC announcer voices, before they went all regional.

Sim took a step back, looking up into the lens. ‘Mrs Chung? It’s the police.’

Inside, the dog was going mental. Barking and barking and barking.

‘Can I see some identification please? ’

As if the ninja black outfit with stab-proof vest, airwave handset, utility belt, and bowler hat with a chequered band around it wasn’t enough. Sim held her warrant card up to the camera. ‘We need to talk to you about Anthony.’

A pause. Then, ‘Yes. Yes, of course. . .’ Click. The intercom went silent.

Sim puffed out her cheeks. ‘How do you want to play this, Guv? ’

‘Rock, paper, scissors? ’
