‘You used to be the house-detective,’ he croaked. ‘At the Adlon. I once cased the place to do a job.’ He chuckled hoarsely. ‘Am I right?’

‘You’ve got a good memory,’ I said, lighting one myself. ‘That was quite some time ago.’

His grip tightened. ‘Don’t worry,’ he said. ‘I won’t tell anyone. Anyway, it’s not like you were a bull, is it?’

‘You said you were casing the place. What particular line of criminality were you in?’

‘I was a nutcracker.’

‘I can’t say as I recall the hotel safe ever being robbed,’ I said. ‘At least, not as long as I was working there.’

‘That’s because I didn’t take anything,’ he said proudly. ‘Oh, I opened it all right. But there was nothing worth taking. Seriously.’

‘I’ve only got your word for that,’ I said. ‘There were always rich people at the hotel, and they always had valuables. It was very rare that there wasn’t something in that safe.’

‘It’s true,’ he said. ‘Just my bad luck. There really was nothing that I could take that I could ever have got rid of. That’s the point, you see. There’s no point in taking something you can’t shift.’

‘All right, I believe you,’ I said.

‘I’m not boasting,’ he said. ‘I was the best. There wasn’t anything I couldn’t crack. Here, I bet you’d expect me to be rich, wouldn’t you?’

I shrugged. ‘Perhaps. I’d also expect you to be in prison, which you are.’

‘It’s because I am rich that I’m hiding here,’ he said. ‘I told you that, didn’t I?’

‘You mentioned something about that, yes.’ I took my time before I added: ‘And what have you got that makes you so rich and wanted? Money? Jewels?’

He croaked another short laugh. ‘Better than that,’ he said. ‘Power.’

‘In what shape or form?’

‘Papers,’ he said. ‘Take my word for it, there’s an awful lot of people who’d pay big money to get their hands on what I’ve got.’

‘What’s in these papers?’

His breathing was shallower than a Der Junggeselle cover-girl.

‘I don’t know exactly,’ he said. ‘Names, addresses, information. But you’re a clever sort of fellow, you could work it.’

‘You haven’t got them here, have you?’

‘Don’t be stupid,’ he wheezed. ‘They’re safe, on the outside.’ I took the dead cigarette from his mouth and threw it onto the floor. Then I gave him the rest of mine.
