In the street below a police whistle shrieked, and a fusillade of pistol shots woke scandalised echoes.

Bending almost double Lanyard moved rapidly northward on the footway beside the western tracks, and so gained the old station on the west side of Fifty-eighth Street, for years dedicated to the uses of desuetude. Through this he crept, then down the stairs, encountering at the lower landing an iron gate which obliged him to climb over and jump.

Not a soul paid the least attention to this matter of a gentleman in evening dress without hat or top coat dropping from the stairway of a disused elevated station at two o'clock in the morning.

In New York anything can happen, and most things do, without stirring up meddlesome impulses in innocent bystanders.

FORCE MAJEURE

This visit to his rooms was the briefest of the several Lanyard made that night, considerations of mortal urgency dictating its drastic abbreviation.

If the events of the last few hours had meant anything whatever they had demonstrated two truths which shone like beacon lights: that Manhattan Island was overpopulated as long as both he and Ekstrom remained on it; that Ekstrom had been goaded to the verge of aberration by the discovery that Lanyard had come safely through the Assyrian débâcle to take up anew his self-appointed office of Nemesis to the Prussian spy system in general and to the genius of its American bureau in particular.

Henceforth that one would know no more rest while Lanyard lived.

Thus that little street-level apartment forfeited whatever attractions it originally had possessed in the adventurer's estimation. Not only was the address known to Ekstrom's associates, and so open to him, but its peculiar characteristics, its facilities for access from the street direct, rendered it a highly practicable death-trap for a hunted man.
