“Same as the original ransom note, if I recall.”
“Anything else?”
“First class stationery.” He held it to the light. “Wonder where they got it. Why don’t you look into the watermark?”
“I already put Research on it.”
“So now they’re threatening his business.”
“It’s easy to make an ‘accident’ at a construction site.”
“Unless it’s a feint while they take another shot at his daughter.”
“If they do,” said Bell, “they’ll run head-on into Harry Warren’s Gang Squad. Harry’s blanketed 13th Street.”
Van Dorn showed his teeth in a semblance of a smile. “Good . . . But how long can I afford to take Harry’s boys off the gangs? ‘Gophers’ and ‘Wallopers’ are running riot, and the Italians are getting bolder every day.”
“A dedicated Van Dorn Black Hand Squad,” said Bell, “would free your top gang investigators to concentrate on the street gangs.”
“I’ll think about it,” said Van Dorn.
“We would be better fixed to attack the Black Hand.”
“I said I’d think about it.”
Isaac Bell strode uptown from the 125th Street subway station through a neighborhood rapidly urbanizing as new-built sanitariums, apartment blocks, tenements, theaters, schools, and parish houses uprooted Harlem’s barnyards and shanties. He was a block from 128th Street, nearing a jagged hill of rock that Giuseppe Vella was excavating for the Church of the Annunciation, when the ground shook beneath his feet.
He heard a tremendous explosion. The sidewalk rippled. A parish steeple swayed. Panicked nuns ran from the building, and Convent Avenue, which was surfaced with vitrified brick, started to roll like the ocean.
Bell had survived the Great Earthquake in San Francisco only last spring, awakening suddenly in the middle of the night to see his fiancée’s living room and piano fall into the street. Now, here in Manhattan, he felt his second earthquake in months. A hundred feet of the avenue disintegrated in front of him. Then bricks flew, propelled to the building tops by gigantic jets of water.
It was no earthquake, but a flood.
A river filled Convent Avenue in an instant.
There could be only one source of the raging water. The Croton Reservoir system up north in Westchester supplied New York City’s Central Park Reservoir via underground mains.
The explosion in Giuseppe Vella’s excavation—an enormous dynamite “overcharge,” whether by miscalculation or sabotage—had smashed them open. In an instant, the “water famine” predicted by Catskill Aqueduct champions seemed unbelievable.
A liquid wall roared out of Convent Ave and raced down it, tearing at first-story windows and sweeping men, women, and horses around the corners and into the side streets. Its speed was startling, faster than a crack passenger train. One second, Isaac Bell was pulling the driver from a wagon caught in the ice-cold torrent; the next, he himself was picked up and flung into 127th Street. He battled to the surface and swam on a foaming crest that swept away shanties the full block to Amsterdam Avenue.
There the water careened downhill, following the slope of the land south. Bell fought out of the stream and dragged himself upright on a lamppost. Firemen from a nearby station were wading in to pull people out.
Bell shouted, “Where are the water gates?”
“Up Amsterdam at 135th.”
Bell charged up Amsterdam Avenue at a dead run.
A third of a mile north of the water main break, he found a sturdy Romanesque Revival brick and granite castle. The lintel above its iron doors was engraved WATER DEPARTMENT. A structure this big had to be the main distributing point for the Westchester reservoirs. He pushed inside. Tons and tons of Croton water were surging up from a deep receiving chamber into four-foot-diameter cast-iron pipes. The pipes were fitted with huge valve wheels to control the outflow to the mains breached seven blocks away by the explosion.
Bell spotted a man struggling with them. He hurtled down a steel ladder and found an exhausted middle-aged engineer desperately trying to close all four valves at once. He was gasping for breath and looked on the verge of a heart attack. “I don’t know what happened to my helper. He’s never late, never misses a day.”
“Show me how to help!”
“I can’t budge the gates alone. It’s a two-man job.”
With the dynamite explosion no accident, thought Bell, but a coordinated Black Hand attack to blame Giuseppe Vella for flooding an entire neighborhood, the extortionists must have left the helper bloodied in an alley.
