'My uncle had one on his bunch.'
'And that bunch is in your possession?'
'Yes, and has not been out of it. It is locked up in my bureau.'
'Very well, then, the fellow did not get in by that means. Had anyone else a key?'
'Yes, Mrs. Cusworth.'
'And is there a third?'
'No; that is all.'
'Where was Mrs. Cusworth's key on the night in question?'
'I did not inquire. It was unnecessary.'
'Not at all unnecessary. If the man did not obtain access by your key, he did that of by the housekeeper.'
