It was only the merest flicker of light and understanding that came to the little man’s eyes, but Elk saw it.
“Tell him I believe I left it with the Wandsworth man,” he said.
“Um!” said Elk, and went back to the waiting Hagn.
“He said he left it in the Pentonville Road,” said Elk untruthfully, but Mr. Hagn seemed satisfied.
Returning to the cells, Elk saw the gaoler.
“Has this man asked you where he was to be taken from here?”
“Yes, sir,” said the officer. “I told him he was going to Wandsworth Prison—we usually tell prisoners where they are going on remand, in case they wish to let their relatives know.”
Elk had guessed right. The inquiry about the key was prearranged. A telephone message to Mary Lane, where the remainder of the gang were held, produced the curious information that a woman, reputedly the wife of one of the men, had called that morning, and, on being refused an interview, begged for news about the missing key of the coal cellar, and had been told that it was in the possession of “the Brixton man.”
“The men are to be remitted to Wormwood Scrubbs Prison, and they are not to be told where they are going,” ordered Elk.
That afternoon a horse-driven prison-van drew out of Cannon Row and rumbled along Whitehall. At the juncture of St. Martin’s Lane and Shaftesbury Avenue, a carelessly-driven motor lorry smashed into its side, slicing off the near wheel. Instantly there came from nowhere a crowd of remarkable appearance. It seemed as if all the tramps in the world had been lying in wait to crowd about the crippled van. The door was wrenched open, and the gaoler on duty hauled forth. Before he could be handled, the van disgorged twenty Central Office men, and from the side streets came a score of mounted policemen, clubs in hand. The riot lasted less then three minutes. Some of the wild-looking men succeeded in making their escape, but the majority, chained in twos, went, meekly enough, between their mounted escorts.
