About the Book

NEW YORK TIMES BESTSELLER * Jane Rizzoli and Maura Isles - the inspiration for the smash hit TNT series - continue their bestselling crime-solving streak, as they pursue a shadowy psychopath keeping secrets and taking lives.

"Suspense doesn't get smarter than this." - Lee Child

Two separate homicides, at different locations, with unrelated victims, have more in common than just being investigated by Boston PD detective Jane Rizzoli and medical examiner Maura Isles. In both cases, the bodies bear startling wounds - yet the actual cause of death is unknown. It's a doubly challenging case for the cop and the coroner to be taking on, at a fraught time for both of them. As Jane struggles to save her mother from the crumbling marriage that threatens to bury her, Maura grapples with the imminent death of her own mother - infamous serial killer Amalthea Lank.

While Jane tends to her mother, there's nothing Maura can do for Amalthea, except endure one final battle of wills with the woman whose shadow has haunted her all her life. Though succumbing to cancer, Amalthea hasn't lost her taste for manipulating her estranged daughter - this time by dangling a cryptic clue about the two bizarre murders Maura and Jane are desperately trying to solve.

But whatever the dying convict knows is only a piece of the puzzle. Soon the investigation leads to a secretive young woman who survived a shocking abuse scandal, an independent horror film that may be rooted in reality, and a slew of martyred saints who died cruel and unusual deaths. And just when Rizzoli and Isles think they've cornered a devilish predator, the long-buried past rears its head - and threatens to engulf more innocent lives, including their own.
