with something like the snarl of an animal. "Look at that! Look at that, will you?" he almost shouted. Hadley blinked at it and Ralston got up and took the handkerchief in his hand. "It seems to be the orthodox thing," he said with interest. "Seems to be! Seems to be pretty conclusive, I should say. It's proof!" "It's proof that Dr. Underwood has a malicious enemy and a rather stupid one," said Burton, thinking that it was time for him to take a hand in this remarkable scene. "I found that handkerchief an hour ago, tucked behind one of the books there, where you would certainly have found it if you had made any search. It is, of course, perfectly evident that it was placed there for the express purpose of having you find it." "I don't see that that is so evident," Selby interrupted. "What have you got to say about this, anyhow?" "Do you think that if Dr. Underwood had had such an incriminating piece of evidence he would have kept it instead of destroying it? If he were bound to keep it, do you think he would hide it where the first careless search would bring it to light? If he had so hidden it, would he have invited you here to search? You can't answer yes to those questions, unless you think he is a fit subject for the insane asylum rather than the jail." Leslie shot him an eloquent glance of thanks. Hadley coughed and looked at Ralston, who was attending to Burton closely. "I agree with you perfectly," the editor said, and Hadley nodded. Selby turned a face of deliberate insolence upon Burton. "I don't know who you are, Mr. Burton, but you are here as a friend of Dr. Underwood's, that's clear." "Yes," said Burton. "I love him for the enemies he has made." Ralston looked at him with evident enjoyment. "Well, a friend's say-so won't go very far in clearing a man when facts like these stand against him. We're here looking for a thief. If it wasn't Dr. Underwood that held me up, let him explain that handkerchief, found here in his own private room." And Hadley sagely nodded. "I can't explain it," said Dr. Underwood. The life had gone out of his voice. "It explains itself," said Burton impatiently.
