A particularly nasty case falls on Detective April Woo's plate just as she's cramming for the NYPD sergeant's exam: the strangling and hanging of an Upper West Side salesgirl as she was at the point of closing her store just a few steps away from April's precinct house. Albert Block, the accountant across the street, soon confesses to Maggie Wheeler's murder, but even though he knows a few choice details about the crimewhat Maggie was wearing when she was strung up, for exampleApril and her colleagues don't believe him. And they're right, because we know even before a second salesgirl is killed over on the East Side that the murderer is dangerously unbalanced Camille Honiger- Stanton. Or is it, after all? Could the pushy redhaired killer with the friendly dog actually be a transvestite impersonation by Camille's boyfriend Nathan Bouck, the brutal caretaker who keeps her confined in a straitjacketor a masquerade by her sister Milicia, a glamorous architect who's tearfully consulted April's psychiatrist friend Jason Frank about her out-of-control sister? Just as long as April and Jason's debut (Burning Time, 1993), and even less propulsive, since the regulars' continuing problems don't make them continuously engaging.
