The tenth novel in the New York Times bestselling Longmire series, featuring Sheriff Walt Longmire.

Walt Longmire is sinking into high-plains winter discontent when his former boss, Lucian Conally, asks him to take on a mercy case in a neighbouring county. An old friend, Detective Gerald Holman, has taken his own life, and Lucian wants to know why. With the clock ticking on the birth of his first grandchild, Walt learns that the by-the-book detective might have suppressed evidence concerning three missing women.

Digging deeper, Walt uncovers an incriminating secret so dark that it threatens to claim other lives even before the sheriff can serve justice … Wyoming style.
