'Then No. 3 must have come on behalf of Mr. Ravengar, sir,' said Albert.

'You are no doubt right,' Hugo agreed. 'But how did you know that?'

'Hawke's Detective Agency, sir. I found out before my wedding that one of their men had been hanging about here, so I chummed up to him. I spun him a yarn how I'd been with Hawke's once, and they gave me the bag, and I wasn't satisfied, and he'd got a lot of grievances against Hawke's, too, he had. We got very friendly. Pity I had to leave the thing for my wedding. But I came back after a week.'

'Yes, that he did, sir,' said Lily proudly, 'and insisted on it.'

'I soon knew they were going to burglarize this flat to get some phonograph records.'

'Phonograph records!' Hugo repeated, pondering.

'Yes, sir; and so I thought I'd be beforehand with 'em.'

'Why didn't you tell me directly you knew?'

'You gave me that Gaboriau book to read, sir, and I learnt a lot from it. It's put me up to a power of things. And, amongst others, that two people can't manage one job. One job, one man.'

'You'll excuse Albert, sir,' said Lily; 'that's only his way of talking.'
