Now you remember I'd seen him coming out of Daley's room earlier, eh?
Well, it seems that Sawyer saw a chance to put up a game on me.

So after I'd gone upstairs again, he sneaked back to 'Horace's' room, got that confounded blue-book of Upton's and waited his chance.

After we'd left the room he came up here and slid the thing among some books on the table there.

While he was in here Durkin came along and knocked and Sawyer slipped over and locked the door.

Then he waited until he thought Durkin had gone and unlocked the door again and came out.
