I remembered perfectly putting the thing behind my head before I went to sleep, and now it had vanished utterly.

Of course I could not advertise my loss, and I didn't greatly mind it, for this was not a job where I could do much shooting.

But it made me think a good deal about Mr Gresson.

He simply could not suspect me; if he had bagged my gun, as I was pretty certain he had, it must be because he wanted it for himself and not that he might disarm me.

Every way I argued it I reached the same conclusion.
