In Isola, the hours between midnight and dawn are usually a quiet time. But for the 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.
