"He has been on his guard all along, yet we found him out.

For that matter, any man who lives regularly at the Mansion House these days is open to our suspicion." For the Mansion House, ever since Tom's having been ordered away, had been a losing proposition.

Now and then a traveling salesman stopped there, though not many.
"By the way, Harry," predicted Tom, as the chums were riding back to Paloma at the close of the afternoon, "look out, in about three of four days, for a new and permanent guest at the Cactus House." "Who's coming ?" inquired Hazelton.
"Whatever man the Colthwaite Company decides to send to the Cactus House as soon as headquarters in Chicago receives Ransom's report.

I think we'll know that new chap, too, when he shows up.

Also, you'll find that the new man is either an avowed enemy of Ransom, after a little, or else he won't choose to know Ransom at all." "That's pretty wild guessing," scoffed Harry Hazelton.
"Wait three or four days, and see whether it's guessing or one of the fine fruits of logic," proposed Reade.
