of inquiry opened by Trent, Mr. Murch for the first time put a question.
'Then you left him telephoning by the open window, with the lights on, and the drinks on the table; is that it?'
'That is so, Mr. Murch.' The delicacy of the change in Martin's manner when called upon to answer the detective momentarily distracted Trent's appreciative mind. But the big man's next question brought it back to the problem at once.
'About those drinks. You say Mr. Manderson often took no whisky before going to bed. Did he have any that night?'
'I could not say. The room was put to rights in the morning by one of the maids, and the glass washed, I presume, as usual. I know that the decanter was nearly full that evening. I had refilled it a few days before, and I glanced at it when I brought the fresh syphon, just out of habit, to make sure there was a decent-looking amount.'
The inspector went to the tall corner-cupboard and opened it. He took out a decanter of cut glass and set it on the table before Martin. 'Was it fuller than that?' he asked quietly.
