Sheriff Walt Longmire is sinking into a high-plains winter discontent when his former boss Lucian Connally asks him to take on a special case. A detective is dead, and Lucian wants to know what drove this by-the-book lawman to take his own life. With the clockticking on the birth of Walt's first grandchild, he enlists the help of his friend Henry Standing Bear and undersheriff Vic Moretti, and ends up elbow-deep in a cold case involving three missing women. Walt follows the blood trail from a casino in Deadwood to a lodge in the snowy Black Hills of South Dakota and to a shady strip club in the neighboring county, uncovering a secret so dark it threatens to claim other lives before the sheriff can serve justice-Wyoming style. Book #10, 317 pages, soft cover, ISBN 9780143126973.
