With his free hand, The Shadow manipulated the bars that restrained Harry Vincent. They seemed to break beneath his touch. Only for a second did a tiny steel instrument gleam in the hand that broke the fetters, thus revealing the method that the man of mystery employed.
Harry scrambled from the chair. He needed no instructions. He went to the side of Clyde Burke to cut the straps that bound the helpless man to the operating table.
Oddly enough, Harry performed this action with the very knife that Palermo had held. The murderer had dropped it when The Shadow had entered.
The Shadow had moved away from the opening to the roof. There Palermo saw the explanation of the amazing arrival of The Shadow.
On the roof rested a strange machine — an autogiro. Long horizontal arms extended from the top of the remarkable airplane — arms that revolved slowly like the wings of a Dutch windmill.
Descending almost vertically, the remarkable machine had stopped upon the roof with only a single turn of its wheels!
Although his work had been foiled, Palermo still plotted. The Shadow had arrived; now he must depart, carrying his two aids with him.
Palermo had taken a special precaution. When he had entered that evening, he had been followed by none other than Stanley Warwick. Even now, the detective was posted in the lobby of the Marimba Apartments, waiting word from his secret master.
Palermo’s one thought was to temporarily avoid The Shadow’s vengeance. If he could communicate with Warwick — and he had a means of so doing — he might defeat The Shadow at this late moment!
THE SHADOW’S immediate actions brought keen disappointment to Palermo. The man in black pointed to Hassan, and waved the Arab toward the chair where Harry Vincent had been held prisoner.
