They went on to an area called Frenchtown, where women and children were sold by the hour for sexual use and pleasure. There were evenings when only clients in formal evening clothes were allowed in and the whores were trained to speak with men of the upper classes and wore the most elegant and revealing gowns. Some of the houses were fitted with velvet couches and beds covered with silk duvets; others were filthy, dimly lit, tragic storehouses of sorrow and flesh. Within such places, some of those on sale were considered more desirable if they possessed abnormalities, exactly what the Professor wished to find. Coralie waited in the carriage while her father visited two of these wretched houses, one where boys were clothed in dresses, wearing rouge and color on their lips, the other a grim tenement filled with girls dolled up in oversized gowns, costumes that only served to show how very young they were. Neither house was the least bit interesting to the Professor, and he left both quickly enough. But at the second house he was followed by a heavyset man who had with him a child no older than six. The man did his best to get the Professor’s attention as he toted the girl in a rope sling, for she had neither arms nor legs.

“Here’s what you’re looking for,” the man shouted. “She’ll be to your liking. You can have her for a fair price.”

The child had begun to wail, but one smack from her caretaker and she hushed quickly enough. She appeared too stunned to cry any more. The Professor shook his head and stalked away. Still, the brutal man called after him. “You said you wanted a monster. She’s right here! Look no further.”

“What will happen to the child?” Coralie asked after they had climbed into the carriage, escaping the stranger’s escalating rage.

“Go on,” the Professor told the liveryman.

Coralie cast a swift backward glance to watch the child dragged away to what was surely a dreadful fate. The Society for the Prevention of Cruelty to Children had tried to stop children from being allowed to beg, or solicit alms, or be in shows of acrobatics or be included in any immoral or indecent exhibition, especially those presenting an unnatural physical formation. But, in truth, such laws were rarely enforced. Children were not recognized as having rights.

“It’s not our business,” the Professor remarked, sure of himself. “We are here on behalf of science.”

“Perhaps it should be,” Coralie protested. “I could take care of her. It would be no trouble.” The tears that had refused to fall before came freely to her now, though she was quick to wipe them away.

“If you tried to right all the wrongs in the world you’d exhaust yourself in under an hour. This is God’s business.”

“Is it?” Coralie wondered aloud. “Is it not our business to help in God’s work?”

“Our business is to acquire a creature that will draw a crowd, and thereby pay for food and coal and the shoes upon your feet.”

When Coralie strained to see behind them now, the street was empty. The man and his charge had vanished, engulfed by the darkness. It seemed as though they had left God’s sight in this part of the city where human beings were bought and sold as if they were sheep ready for market. “It should be against the law for men to be so cruel,” Coralie pronounced.

“That man is her father.” The Professor turned to his daughter, so that he would not be misunderstood. “And to all the world, he’s well within his rights.”

The Professor had already set in motion his plan for their renewed success. In the first months of 1911 a rumor had begun, one that had been formed inside the Professor’s mind. A monster had settled in the Hudson River, and if a man stood on the banks he might spy it swimming in the dark. Or perhaps it could be sighted at the first light of daybreak, when the water was silver and still. The first to take up the story were two boys fishing for their families’ suppers. They vowed a strange river creature had stolen the catch from their lines; when questioned by the police, each swore it wasn’t a shark, which were abundant in New York Harbor, some reaching fourteen feet long. True, they’d seen a flash of scales set upon the creature’s spine, but it was something entirely different, a being that was dark and unfathomable, almost human in its countenance, with fleet, watery movements. A panic went up. Constables in rowboats patrolled the shores, from the docks downtown all the way up to the Bronx. Several men on the ferries on the four lines which ran from Twenty-third Street to New Jersey leapt into the frigid depths as if they could walk on water, insisting they had heard a woman’s voice call to them, convinced someone had been drowning.
