February in the Hudson Valley brings a new murder mystery for veterinarian Dr. Kate to solve--two bodies, one a man atop the ice of Lover's Lake, the other apparently his woman, frozen face up under the water. Tragically, the young couple had just been married, and when they learn their animal hospital's tranquilizers had been used in the murders, it is up to Dr. Kate and her vet tech Mari to stop the murderer before he strikes again.
