The ruse worked. Both his captors thought that he had again weakened beneath the strain, and they stopped the torture to let him regain strength.

Harry was too wise to extend his period of rest too long. He knew that an overindulgence in that practice would give the game away. Yet why was he waiting at all? He had no hope of rescue.

The Shadow had no inkling of his distress. When Monk Thurman would arrive, some new and more drastic punishment would follow.

Harry showed some signs of life, and Anelmo began the torture again. This time he worked more slowly. At first it was agonizing; then Harry managed to brace himself against it. But at length Anelmo gave the iron rod a peculiar twist, and gained an unexpected result.

Harry screamed despite himself. Genara spoke rapidly. Anelmo tried the new twist with the same result. Harry could stand no more. He was about to give up all his efforts to conceal The Shadow’s secret phone number, when he saw Genara raise a warning hand. The Sicilian was listening.

Silence pervaded the room. Genara opened the inner door, and went out into the dark passageway.

Harry could hear the sound now. A quick rap; then two slow raps. He could barely see Genara in the darkness. The Sicilian rapped twice in response. His raps were quick. Then came two slow taps from the other side.

Genara fumbled with the bolts that held the heavy door. Then he turned the key in the lock. The door opened outward; but no one entered. At least, neither Harry Vincent nor Tony Anelmo could see any one enter.

They stared at John Genara. The Sicilian killer seemed to be backing away from the door. He came into the light of the room. His hands were raised above his shoulders.

Then a gasp of gladness came from Harry Vincent. As Genara turned sidewise, in response to some inaudible command, another figure came in view — the black-clad form of The Shadow!
