You will not move from early morning until you go to bed at night, without being watched.

To prove what I say--you see the man who is reading an evening paper under the gas-lamp there?
Yes?
He is one of Selingman's men.

He is watching us now.

More than once he has been at our side.

Scraps of conversation, or anything he can gather, will go back to Selingman, and Selingman day by day pieces everything together.
