Chinatown Beat

At the start of Chang's promising debut, NYPD detective Jack Yu must cope with his father's recent death and investigate the rape of a grade-school girl on the fringes of Chinatown, where he grew up and has just been stationed. Meanwhile, would-be gangster Johnny Wong is carrying on with Mona, the gorgeous mistress of his employer, Uncle Four, head of the local branch of the Hip Ching tong and a powerful underworld figure in both New York and Hong Kong. As Yu digs deeper into his case, suspecting that an illegal Chinese immigrant may be the serial rapist he is seeking, he finds evidence of a connection between the rapist and the local gangsters. Though Chang builds less suspense than more seasoned police procedural authors, he presents a fascinating look at New York's Chinese-American urban community and its subcultures. (Nov.)
