The wooden walkway was flanked by elevated rail and trolley tracks and crowded with an evening rush of men walking home from work in Manhattan. Trains and streetcars hurtled past. They were packed with humanity, and Bell—who had spent many years tracking criminals on horseback in the open spaces of the West—understood those who preferred to walk in the cold, even assaulted by the constant shriek and rumble of train wheels.

Kent shot a glance over his shoulder. Bell removed his distinctive broad-brimmed white hat and moved side to side to be shielded by the crowds. His quarry hurried against the foot traffic, head down, staring at the boards and ignoring the dramatic panorama of New York’s skyscraper lights and the twinkling carpet of red, green, and white lanterns shown by the tugboats, schooners, steamers, and ferries plying the East River two hundred feet under the bridge.

The stairs on the Manhattan side led down to the City Hall district. The instant Kent hit the pavement he spun on his heel and hurried back toward the river he had just crossed. Bell followed, wondering what Kent was up to as they neared the waterfront. South Street, which passed under the bridge and paralleled the East River, was bordered by a forest of ship masts and bowsprits. Finger piers and warehouses thrust into the stream, forming slips in which moored three-masted sailing ships, tall-funneled steamers, and railroad barges.

Kent turned uptown, away from the Brooklyn Bridge. He hurried for several blocks, walking fast, not bothering to look back. When he reached Catherine Slip, he turned toward the water. Bell saw trading vessels rafted side by side. Deck cranes swung pallets of freight from ship to shore. Longshoremen trundled them into the warehouses. Kent passed the ships and headed for a long and unusually narrow steam yacht, which had not been visible from South Street.

Bell observed from the corner of a warehouse. The narrow yacht, which was fully one hundred feet long, had a sleek knife blade of a steel hull painted white, a tall steering bridge amidships, and a tall smokestack aft. Despite its businesslike appearance, it was luxuriously finished with brass fittings and varnished mahogany. Moored incongruously among the grimy trading vessels, it was, Bell thought, well hidden.

Farley Kent dashed up a gangway. Lighted portholes gleamed from the low cabin. Farley Kent pounded on the door. It opened, spilling light, and he disappeared inside and yanked it shut. Bell followed immediately. He put his hat on his head and crossed the pier with quick, firm strides. A deckhand on one of the trading vessels noticed. Bell gave him a grim stare and a dismissive nod, and the man looked away. Bell confirmed that the yacht’s decks were still empty of sailors, stepped quietly across the gangway, and pressed his back to the bulkhead that formed the cabin.

Removing his hat again, he peered in a porthole cracked open for ventilation.

The cabin was small but luxurious. Brass ship lamps cast a warm glow on mahogany paneling. In a swift glance, Bell took in a sideboard with crystal glasses and decanters secured in racks, a dining table set within a horseshoe banquette with green leather upholstery, and a voice pipe for communicating throughout the vessel. Hanging over the table was a Henry Reuterdahl oil painting of the Great White Fleet.
