Twenty-four years ago, teen prodigy Thea Janis vanished from her upper crust Boston prep school. At first called a runaway, she's later named among the victims of a serial killer, a man doing life in Walpole Prison.

Then a new manuscript appears in her family's mailbox. The words cry out from the printed pages, Thea's voice unmistakable even a quarter century since the girl's mysterious disappearance. A new client bearing a dead man's name turns up in the office of P.I. Carlotta Carlyle, looking for her help in finding whoever is sending the book--even if it turns out to be Thea herself.

The investigation leads Carlotta to a prominent Boston family with deep connections and even deeper pockets, and which badly wants the tragic past to stay buried. But after a hit man tries to write his own ending to the saga, the cold case suddenly goes white hot--and Carlotta may be the one who ends up getting burned.
