Five minutes later he stood close to Rann's house. From the side on which he had approached it was dark. No gleam of light showed through the windows. Slowly he walked around the building, and stopped suddenly on the opposite side. Here a closely drawn curtain was illuminated by a glow from within. Cautiously Aldous made his way along the log wall of the house until he came to the window. At one side the curtain had caught against some object, leaving perhaps a quarter of an inch of space through which the light shone. Aldous brought his eyes on a level with this space.

A half of the room came within his vision. Directly in front of him, lighted by a curiously shaped iron lamp suspended from the ceiling, was a dull red mahogany desk-table. At one side of this, partly facing him, was Culver Rann. Opposite him sat Quade.

Rann was speaking, while Quade, with his bullish shoulders hunched forward and his fleshy red neck, rolling over the collar of his coat, leaned across the table in a tense and listening attitude. With his eyes glued to the aperture, Aldous strained his ears to catch what Rann was saying. He heard only the low and unintelligible monotone of his voice. A mocking smile was accompanying Rann's words. To-night, as at all times, this hawk who preyed upon human lives was immaculate. In all ways but one he was the antithesis of the beefy scoundrel who sat opposite him. On the hand that toyed carelessly with the fob of his watch flashed a diamond; another sparkled in his cravat. His dark hair was sleek and well brushed; his bristly little moustache was clipped in the latest fashion. He was not large. His hands, as he made a gesture toward Quade, were of womanish whiteness. Casually, on the street or in a Pullman, Aldous would have taken him for a gentleman. Now, as he stared through the narrow slit between the bottom of the curtain and the sill, he knew that he was looking upon one of the most dangerous men in all the West. Quade was a villain. Culver Rann, quiet and cool and suave, was a devil. Behind his depravity worked the brain which Quade lacked, and a nerve which, in spite of that almost effeminate immaculateness, had been described to Aldous as colossal.

Suddenly Quade turned, and Aldous saw that he was flushed and excited. He struck the desk a blow with his fist. Culver Rann leaned back and smiled. And John Aldous slipped away from the window.

His nerves were quivering; in the darkness he unbuttoned the pocket that held his automatic. Through the window he had seen an open door behind Rann, and his blood thrilled with the idea that had come to him. He was sure the two partners in crime were discussing himself and MacDonald—and Joanne. To hear what they were saying, to discover their plot, would be three quarters of the fight won, if it came to a fight. The open door was an inspiration.

Swiftly and silently he went to the rear of the house. He tried the door and found it unlocked. Softly he opened it, swinging it inward an inch at a time, and scarcely breathing as he entered. It was dark, and there was a second closed door ahead of him. From beyond that he heard voices. He closed the outer door so that he would not be betrayed by a current of air or a sound from out of the night. Then, even more cautiously and slowly, he began to open the second door.

An inch at first, then two inches, three inches—a foot—he worked the door inward. There was no light in this second room, and he lay close to the floor, head and shoulders thrust well in. Through the third and open door he saw Quade and Culver Rann. Rann was laughing softly as he lighted a fresh cigar. His voice was quiet and good humoured, but filled with a banter which it was evident Quade was not appreciating.

"You amaze me," Rann was saying. "You amaze me utterly. You've gone mad—mad as a rock-rabbit, Quade! Do you mean to tell me you're on the square when you offer to turn over a half of your share in the gold if I help you to get this woman?"

"I do," replied Quade thickly. "I mean just that! And we'll put it down in black an' white—here, now. You fix the papers, same as any other deal, and I'll sign!"

For a moment Culver Rann did not reply. He leaned back in his chair, thrust the thumbs of his white hands in his vest, and sent a cloud of smoke above his head. Then he looked at Quade, a gleam of humour in his eyes.
