“Ah! I must know what it said,” said Nick, as he glanced at it.
Turning to Mr. Mountain, Nick said:
“One of the peculiar features of this affair is the frequent and impudent letters that are written to me.
“Until you came with your story, I was at a loss to understand the reason of them. I do now. Your case is the big one. While it is being worked the Brown Robin would have us think that the other case is the only one it is working on.
“It is quite ingenious and a new way of working. Leaving a trail open on the second, they will carefully make those to the first blind.
“Now, Mr. Mountain, return to your office. Another aid of mine will call on you as soon as he can. His sole business will be to study your appearance. Give him every opportunity.
“If you receive another letter, let him have it. If you receive a notice from the Brown Robin to go to any particular place, tell him of it. That I must know of at the earliest moment.
“Now, Patsy, Chick is over somewhere in Seventeenth Street. Find him and send him to Mr. Mountain’s office. Now get away, please, both of you, for I must go out.”
Mr. Mountain returned to his office, feeling a weight off his shoulders, since the celebrated Nick Carter had the case in hand.
Patsy hurried off to find Chick.
