The frozen dead

Summary: "In a snowbound valley, deep in the French Pyrenees, a dark story of madness and revenge is unfolding. The first victim is a horse: its headless, flayed body hangs suspended from the edge of a frozen cliff. On the same day as the gruesome discovery takes place, Diane Berg, a young psychiatrist starts her first job at a high security asylum for the criminally insane, just a few miles away. She is baffled by the slightly unorthodox methods the asylum's director uses, and then greatly alarmed when she realizes that drugs are disappearing from within the fortified institution while someone seems to be slipping out at night. Commandant Martin Servaz, a charismatic, Toulouse city cop fond of quoting Latin, can't believe he has been called out over the death of an animal. But there is something disturbing about this crime that he cannot ignore. Then DNA from one of the most notorious inmates of the asylum, a highly intelligent former prosecutor who is accused of killing and raping several women, is found on the corpse... and a few days later the first human murder takes place. Servaz and his colleague, the mysterious Irene Ziegler, must use all their skill to solve the terrifying mystery"--
