The day Sacha found out he could see witches was the worst day of his life. . . .

Being an Inquisitor is no job for a nice Jewish boy. But when Sacha Kessler learns he can see witches, he’s yanked out of everyday life on Hester Street and apprenticed to the New York Police Department’s star Inquisitor, Maximillian Wolf.

The Inquisitor’s mission is to stop magical crime. And New York at the beginning of the twentieth century is a magical melting pot where each ethnic group has its own brand of homegrown witchcraft and magical gangs rule the streets from Hell’s Kitchen to Chinatown.

Soon Sacha has teamed up with fellow apprentice Lily Astral, daughter of one of the city’s richest Wall Street Wizards—and a spoiled snob, if you ask Sacha. Their first job is to find out who’s trying to kill Thomas Edison.

Edison has invented a mechanical witch detector that could unleash the worst witch-hunt in American history. Every magician in town has a motive to kill him. But as the investigation unfolds, all the clues lead back to the Lower East Side. And Sacha soon realizes that his own family could be accused of murder!
