"Wh--what the devil do you mean?"

"No use bluffing," Garth said. "You give yourself away. But don't get too scared. I'm the only one who knows."

The other's voice was scarcely audible.

"Who are you?"

Garth threw back his coat lapel, displaying momentarily his badge.

Black's voice rose on a shrill note.

"It's a lie! It's a lie!"

Garth shook his head.

"I watched you last night," he said, "planting money here and there--a pretty, generous fancy, just to give people the joy of finding it. Men don't do such things in their right senses. I've heard of it, but the fact that you were the brother-in-law of the head of an organization that was after these cases offered a more likely explanation. Put me off the track. Thought you were working for him. Now that I've had a good look at you, there's no question."

Black made a last pitiful effort.

"This is blackmail."

"I have my price," Garth admitted.

Black sat on the table edge.

"I'll put them on to you down town--through Manford."

Garth laughed outright.

"You! You'd never have the nerve. Give a police surgeon one good look at you!"

Black fumbled in one of the drawers. He lifted out a cheque book.

"How much?" he asked with dry lips.

"Not money," Garth said.

He felt every nerve in his body tighten.

"When I saw you making a fool of yourself last night," he went on, "you had come straight from a house you are going to get me in to-night."

The cheque book fluttered to the floor.

"Wh-what for?"

"To save a woman," Garth answered. "It's enough for you to know that they've trapped her there, and that she means too much to me--"

Black turned on him with a snarl.

"You mean you love her. Then maybe you can understand. What about my wife?"

"Black," Garth said quietly, "you stand a better chance of sparing your wife if you meet my price. I promise to do all I can to keep you out of the scandal. I'll get you away clean if it can be done. All I ask is, that for your wife's sake, you'll try to be a man. But now you listen.

By gad, if you refuse to do this thing, I'll raise a scandal that will finish you once for all. I'll shout the thing from the housetops. I'll take you to a cell within the next ten minutes. What about your wife then? Look at me. I'm not bluffing. I hate it, but I've no choice. It's life and death to me, and, since it's all I've got, I'm going to use your reputation to make it life."

Black sank into a chair, covering his face.

"You do mean it. I can't do it. I tell you I can't do it."

Garth stood over the man. As he fought, there came back to him with an advocacy not to be denied, the memory of Nora's altered face, out of which, however, her eyes, unalterable, had glanced at him with a definite appeal.

"Yes you can," he said savagely. "They'll let you vouch for a--friend.

And if you don't, you'll give the game away to a jury and a crowded courtroom."

Black's hands dropped. He stared straight ahead. He did not answer.

Garth reached out and grasped the telephone. Black stumbled to his feet and tore at Garth's arm.

"What are you going to do?"

"Call for a patrol wagon to drive up to your exalted home."

"No, no, no!"

"Then you agree?"

"You'll come with me alone?"

"Yes."

"Then I agree."

The gleam in Black's eye was revealing. It r.e.t.a.r.ded Garth's relief. It warned him that, entering the place alone, he could be handled, as, perhaps, Nora had been handled.

"I'll get my hat and coat," Black said.

"No," Garth answered. "From now on you'll stick to me like a brother."

He took the receiver from the telephone and got the inspector at the station house. While Black protested, he instructed the inspector to have a man follow Black and himself, and, no matter what house they entered, to surround that entire block and to keep a watch on every house front. If he could communicate in no other way, Garth promised to fire his revolver twice, if possible, from a front window.

Black shrank back.

"But you said--alone."

"Alone," Garth answered, "but that's what's going to happen once I'm in.

I'm not throwing my life away. Are you ready, or do you prefer the cell and your picture in the morning papers?"

Black led the way without further protests down the staircase. At the foot he broke down again. Garth warned him and helped him on with his overcoat.

"You leave me no choice," Black whimpered. "No choice."
