Detective Jane Rizzoli is investigating the violent murder of a woman in Boston's Chinatown.

Two strands of silver hair cling to the body - Rizzoli's only clue, but enough for her and Forensic Pathologist Maura Isles to make a startling discovery.

Years earlier, five people died in a horrifying murder-suicide in a restaurant close by. But one
woman connected to that massacre is very much alive, and harbouring a deadly secret.
A secret that will kill again.

Unless Jane and Maura can track it down, and defeat it . . .
