Just in case anybody thought the 47 earlier novels in the 87th precinct were a fluke, McBain's gone and revitalized the routine with Nocturne"". -- The New York Times Book Review

In Isola, the hours between midnight and dawn are usually a quiet time. But for 87th Precinct detectives Carella and Hawes, the murder of an old woman makes the wee hours anything but peaceful -- especially when they learn she was one of the greatest concert pianists of the century long vanished. Meanwhile 88th Precinct cop Fat Ollie Weeks has his own early morning nightmare: he's on the trail of three prep school boys and a crack dealer who spent the evening carving up a hooker.
