"You know as much about it as I do, Brady," replied Matt. "I disappeared from that Hoyne Street house, last night, and I suppose my chum has been getting clues about me and following them up. That's the kind of a lad he is."
"Where did he get any clues that would bring him out here?"
"Give it up."
Brady took a few more turns across the room, presently halting in front of Matt.
"You didn't bring that roll of blue prints to Hoyne Street, last night," said he. "Where did you leave it?"
"Left it out in front of the house," grinned Matt.
Brady started.
"In front of the house?" he echoed.
"Yes."
"Cached?"
