In this intricate, intense mystery from the acclaimed "master of the Quebec thriller," the ghosts of Victor Lessard's past come back to haunt him as he investigates a horrific murder-suicide that doesn't add up.
When a young Montreal family dies in an orgy of bloody violence, all signs point to a rampage by the father. But Victor Lessard isn't convinced. The brilliant, brooding detective suspects that others were involved in the killings. But who? And why? As Lessard struggles to solve the puzzle, the discovery of a nightmarish chamber of horrors seems to confirm that the murders are part of a wider pattern.
Meanwhile, in the Major Crimes Unit, Jacinthe Taillon is investigating the strange kidnapping of Laila François, a former street kid turned webcam girl. Could there be a connection with Lessard's case?
With a ghost from his past making him doubt his own sanity, Lessard must evade the lethal operatives of a powerful, highly secretive organization as he races to untangle the mystery — before a diabolical killer can strike again.
