"Alone?" queried Sam.
"Yes, alone. But I carried a pistol, and I had it ready for use, too."
"I don't blame you," murmured Dick. "And I guess you looked to see if the doors were open, too."
"I did, and smashed out several windows in the bargain. The first place I investigated was that fireplace, and in it I found this." And Tom held up a bit of white paper. On it was printed:
m B. Schlemp uggist. ain St.
"That is from a druggist," said Dick.
"Exactly. I figure out the name is William B. Schlemp, that he is a druggist, and that he is doing business at some number on Main Street," came from Tom. "But I figure out more than that."
"What?"
"The paper was crumpled up, and had in it a few grains of a gray powder. I set the powder on fire and got that strange vapor that almost strangled us."
"You did!" cried Sam. "Then that stuff came from that druggist beyond a doubt."
