"Which room is he in?"
Israels jerked a thumb upwards. "Next landing. Door on left," he ejaculated nervously.
The superintendent pushed by the man. He knew that the critical moment had come. With his quick judgment of men he had summed up Mr. Israels. Whatever the Jew's morals, it was evident that he had a wholesome respect for his own oily skin. He would not risk himself to save the neck of another man. Foyle's intentions were simple. He would steal quietly up the second flight of stairs, burst the door open if it were locked, and seize the man he was in search of in his sleep. But his plans were frustrated.
He had not taken two steps when a woman peeped from an adjoining room. He caught one glimpse of her in the semi-darkness with a police whistle at her
lips. He sprang forward, and as he did so a shrill, ear-piercing blast rang out. Green was close behind him.
She shrieked as the detective tore the whistle from her, and he felt her slender figure entwine itself about him. Down he went, with his companion on top of him, and another woman's loud hysterical cries added to the pandemonium. Foyle picked himself up and, lifting the girl bodily, flung her without ceremony into the room from which she had emerged. From above a voice shouted something, and a knife whizzed downwards and struck quivering in the bare boards of the landing, grazing Green's shoulders.
All need for caution was gone now. Foyle had dropped his jemmy and his hand closed over his pistol. Only as a last resource would he use it, but if he had to—well, there could be no harm in having it handy. A door slammed as the two detectives climbed the second flight of stairs. Green flung himself against the one that had been indicated by Israels, and the flimsy fastening gave way under the shock of his thirteen stone. There was no one in the room. Savagely Heldon Foyle turned and caught the handle of a second door. It turned, and they entered the room, empty like the first, but with an open window looking out on a series of low roofs a dozen feet below. And over the roofs a shadowy figure of a man was clambering hurriedly. He could only dimly be seen.
Green clambered through on to the window-sill and dropped. He was unlucky. A projecting piece of wood caught his foot, and he staggered and lost time. Before he had recovered himself the fugitive was out
of sight, and the sound of his progress had ceased. Foyle called to him to come back and, without waiting to see whether his orders were obeyed, made his way back again to the first-floor landing. Israels was still there, very white and shaky, as the superintendent struck a match.
"Where's that girl?" said the detective curtly. "The one who gave the alarm."
