After a lull of four years, the 'silk stocking rapist' is back at work on the Upper East side, but this time Assistant DA Alexandra Cooper and Detective Mike Chapman have perfect DNA evidence to work with. They also have a much older case to work on - a skeleton has been found entombed in the wall of a house Edgar Allan Poe once lived in, but it turns out to be a relatively modern murder - from 1978. On the day the discovery of this body is leaked to the press, Alex gets a call that the silk stocking rapist has struck again, this time fatally. Or has he? The m.o. isn't precisely the same as the others, and it transpires that the victim worked in Poe's old house in 1978. Are the cases linked or is someone trying to silence possible witness to a thirty-five-year-old murder?
