“Not one of us could swear that Willoughby was there. Neither you nor I could. We never saw him.”

“He wore that disguise,” thundered Thurston. “So you think. But thinking ain’t proof—not by a long chalk.”

Thurston was now almost speechless from rage. Half articulate words of blasphemy were upon his stuttering lips. But Sharkey went coolly on.

“Besides the sympathy of everyone would be with the girl. You can’t succeed that way. You yourself would be covered with ridicule.”

At last the torrent of curses broke forth. “Damn you, Leach Sharkey! That’s what I pay you for, is it? To let that scoundrel slip through our very fingers? And you had the nerve to ask me for another big check this evening. It’s all a confounded plot. You’re bleeding me. Leach is your name, and leech is your nature.” Leach Sharkey rose to his feet. His white teeth gleamed as his short upper lip curled in a contemptuous smile. He raised a threatening finger. It was his turn now to give free vent to profanity.

“Stop right there, you doggoned old fool. I bleed you, do I? Well, take my resignation. All your pay ain’t worth another five minutes of your infernal temper. No man ever dared to browbeat me and insult me as you have done. And now you may go to hell—where you belong.”

The sleuth turned on his heel, and strode to the doorway. But Thurston was after him in an instant, penitent, trembling, ashen pale. He grabbed Sharkey by the coat sleeve.

“No, no, don’t go, I beg of you,” he whined, “I was wrong. I spoke in anger. I apologize. Good God, some one or other will get me within an hour if you leave me unprotected. I haven’t a single friend—no one to stand by me.” There was craven fear in his eyes as he looked timidly around. “I hear the prowling footsteps of my enemies in the night. You alone can save me, Mr. Sharkey.”

“Your damned civility comes too late,” replied the sleuth, as he shook the clutching hands from his shoulder.

“No, no. Don’t say that. Sit down again. See, here is my check book. I’ll pay you that money now—I’ll double the amount—I’ll never haggle with you again. Stay with me till we go East together.”
