I had it on when I came on duty; but it did not keep me from going to sleep.

I awoke to see the room full of people; that is, Miss Trelawny and Sergeant Daw, being only half awake and still stupefied by the same scent or influence which had affected us, fancied that he saw something moving through the shadowy darkness of the room, and fired twice.

When I rose out of my chair, with my face swathed in the respirator, he took me for the cause of the trouble.

Naturally enough, he was about to fire again, when I was fortunately in time to manifest my identity.

Mr.
Trelawny was lying beside the safe, just as he was found last night; and was bleeding profusely from the new wound in his wrist.
