Feet trampled in the room. A man's figure was framed in the lighted window—a bloated bulk that he knew was Spulvedo. A flame shot from that figure into his very face. The missile struck the roof close to his side and splattered shingle and dirt in his face. Without hesitation, he straightened his own arm and fired point blank at the living mark. Spulvedo emitted a stifled shriek and fell from sight.

The window was empty again. Not until long afterward did Martin recall that his conscious mind never received the sound of those two shots.

A dark figure brushed past him and dropped over the edge of the roof to the street. The boatswain followed. Little Billy was by his side, grasping his shoulder.

"Come on—roll off!" the hunchback was urging.

The second window overhead was suddenly alight, and a booming voice was cursing in the room. Martin rolled off the edge and fell into the boatswain's arms.

Then he was on his feet, running, by the boatswain's side. Just in front of him raced the hunchback, and a queer figure in man's clothes, whose long hair streamed behind. He heard men shouting.

They passed the corner and started across the Embarcadero toward the wharves. Far down the street a police whistle was blowing shrilly. Behind them, the Black Cruiser was spewing forth its brood.

The street was wide. They were not nearly across when these sounds of pursuit reached Martin's ears. He heard the pounding of feet behind him, and the sound of shots. He heard the hunchback fling over his shoulder:

"Hold them back, bos! We'll get the boat free!"

The boatswain stopped short and wheeled about. Martin's momentum carried him several steps farther, then he too checked his stride. Intuitively, he knew his place was at the boatswain's side.
