He let himself go loose and relaxed in the air, shot down, and felt the roof take his weight lightly, landing on his toes. He had not only made the leap, but he had landed a full foot and a half in from the edge of the roof.

Compared with the darkness of the interior of the house, everything on the outside was remarkably light now. He could see Denver at the window shaking his head. Then the professional slipped over the sill with practiced ease, dangled at arm's length, and flung himself out with a quick thrust of his feet against the wall.

The result was that while his feet were flung away far enough and to spare, the body of Denver inclined forward. He seemed bound to strike the roof with his feet and then drop head first into the alley below. Terry set his teeth with a groan, but as he did so, Denver whirled in the air like a cat. His body straightened, his feet barely secured a toehold on the edge of the roof. The strong arm of Terry jerked him in to safety.

For a moment they stood close together, Denver panting.

He was saying over and over again: "Never again. I ain't any acrobat,
Black Jack!"

That name came easily on his lips now.

Once on the roof it was simple enough to find what they wanted. There was a broad skylight of dark green glass propped up a foot or more above the level of the rest of the flat roof. Beside it Terry dropped upon his knees and pushed his head under the glass. All below was pitchy-black, but he distinctly caught the odor of Durham tobacco smoke.

CHAPTER 35

That scent of smoke was a clear proof that there was an open way through the loft to the room of the bank below them. But would the opening be large enough to admit the body of a man? Only exploring could show that. He sat back on the roof and put on the mask with which the all-thoughtful Denver had provided him. A door banged somewhere far down the street, loudly. Someone might be making a hurried and disgusted exit from Pedro's. He looked quietly around him. After his immersion in the thick darkness of the house, the outer night seemed clear and the stars burned low through the thin mountain air. Denver's face was black under the shadow of his hat.

"How are you, kid—shaky?" he whispered.
