"I want to send a code message to my firm. Do you think you can follow it?"

"I can try," said the operator.

The code was really Slav; and when the long message was signed it was signed by the name Vroon.

The day after the news came that Florence had jumped overboard off the banks, Vroon with a dozen other men had started out to comb all the fishing villages along the New England coast. Somewhere along the way he felt confident that he would learn whether the girl was dead or alive. If she was dead then the game was a draw, but if she was alive there was still a fighting chance for the Black Hundred. He had had some idea of remaining in the village and accomplishing the work himself; but after deliberation he concluded that it was important enough for Braine himself to take a hand in. So the following night he departed for Boston, from there to New York. He proceeded at once to the apartment of the countess, where Braine declared that he himself would go to the obscure village and claim Florence as his own child. But to insure absolute success they would charter Morse's yacht and steam right up into the primitive harbor.

When Vroon left the apartment Norton saw him. He was a man of impulses, and he had found by experience that first impulses are generally the best. He did not know who Vroon was. Any man who called on the Countess Perigoff while Braine was with her would be worth following.

On the other hand, Vroon recognized the reporter instantly and with that ever-ready and alert mind of his set about to lure the young man into a trap out of which he might not easily come.

Norton decided to follow his man. He might be going on a wild-goose chase, he reasoned; still his first impulses had hitherto served him well. He looked care-worn. He was convinced that Florence was dead, despite the assertions of Jones to the contrary. He had gone over all the mishaps which had taken place and he was now absolutely convinced that his whilom friend Braine and the Countess Perigoff were directly concerned. Florence had either been going to or coming from the apartment. And that memorable day of the abduction the countess had been in the dry goods shop.

Vroon took a down-town surface car, and Norton took the same. He sat huddled in a corner, never suspecting that Vroon was watching him from a corner of his eye. Norton was not keen to-day. The thought of Florence kept running through his head.

The car stopped and Vroon got off. He led Norton a winding course which at length ended at the door of a tenement building. Vroon entered. Norton paused wondering what next to do, now that his man had reached his destination. Well, since he had followed him all this distance he must make an effort to find out who he was and what he was going to do. Cautiously he entered the hallway. As he was about to lay his hand on the newel post of the dilapidated stairs the floor dropped from under his feet and he was precipitated into the cellar.

This tenement belonged to the Black Hundred; it concealed a thousand doors and a hundred traps. Its history was as dark as its hallways.
