"They did. But they didn't find the letter. It was right in plain sight, all the while, though."
"In plain sight?"
"Sure. This man just took an old crumpled envelope, that didn't look good enough to hold a receipted gas bill, and stuck this important letter in it. Then he jabbed it into a card rack, where everyone could see it. The police never suspected for a moment that their man would do such a simple thing, and they passed over this old envelope a dozen times. You see they were looking in the hard places, while, all the while, it was in the easiest place."
"Well, what's the answer?" asked Innis, as Paul came to a stopping place.
"Why can't Dick do the same thing?" asked his chum.
"How do you mean?" that young man wanted to know.
"Why, just get an old advertising envelope, put your papers in that, and jab it up back of that looking glass," and Paul indicated a mirror on a side of the car. "Let part of the envelope stick out, Dick, and if those men search until doomsday they'll never find it."
"I believe you're right!" Dick cried. "I'll do it."
"It will be safer than carrying the papers in your pocket," went on Paul, "for there's no telling when you may be held up, and searched. Your uncle might hire some one to pose as a road agent just to get a chance to go through your clothes."
