‘What time did the police find it?’

‘Seven-thirty.’

‘So between one-thirty in the afternoon and seven-thirty in the evening someone planted it. That’s right, isn’t it?’

‘If anyone planted it.’

‘Well, we won’t argue about that. Sometime between one-thirty and seven-thirty either Perelli or someone brought a fishing-rod into this building. That’s right, isn’t it?’

He couldn’t find any fault with that reasoning.

‘Yep.’

‘Are there any other entrances except the main one?’

‘There’s a rear entrance to the basement.’

‘Can anyone get up to the apartments that way?’
