Book 18 in the acclaimed and number one-bestselling Three Pines series featuring the beloved Chief Inspector Armand Gamache.

'Electrifying drama ... the bodies pile up, the intensity and horror are reminiscent of Thomas Harris at his finest. Gamache is a fascinatingly complex protagonist ... The way Penny explores the meaning of this line from Auden's Twelve Songs: VIII - There is always another story, there is more than meets the eye - makes it one of her very best' BOOK OF THE MONTH, THE TIMES

'Penny delves into the nature of evil, sensitively exploring the impact of the dreadful events she describes while bringing a warmth and humanity to her disparate cast of characters that, unusually for a crime novel, leaves you feeling better about the world once you've finished' BOOK OF THE MONTH, OBSERVER

It's spring and Three Pines is reemerging after the harsh winter. But not everything buried should come alive again. Not everything lying dormant should reemerge.

But something has.

As the villagers prepare for a special celebration, Armand Gamache and Jean-Guy Beauvoir find themselves increasingly worried. A young man and woman have reappeared in the Surete du Quebec investigators' lives after many years. The two were young children when their troubled mother was murdered, leaving them damaged, shattered. Now they've arrived in the village of Three Pines.

But to what end?

Gamache and Beauvoir's memories of that tragic case, the one that first brought them together, come rushing back. Did their mother's murder hurt them beyond repair? Have those terrible wounds, buried for decades, festered and are now about to erupt?

As Chief Inspector Gamache works to uncover answers, his alarm grows when a letter written by a long dead stone mason is discovered. In it the man describes his terror when bricking up an attic room somewhere in the village. Every word of the 160-year-old letter is filled with dread. When the room is found, the villagers decide to open it up.

As the bricks are removed, Gamache, Beauvoir and the villagers discover a world of curiosities. But the head of homicide soon realizes there's more in that room than meets the eye. There are puzzles within puzzles, and hidden messages warning of mayhem and revenge.

In unsealing that room, an old enemy is released into their world. Into their lives. And into the very heart of Armand Gamache's home.
