Blood upon the Snow

Private detective Mark East arrives at Crestwood, an elegant estate, to serve as a private secretary to archaeologist Joseph Stoneman. At least, East is supposed to be a secretary. Mr. Stoneman's nervous manner suggests that he's actually in need of a bodyguard. The estate's other residents-including a troubled hostess who confines herself to her room and a strangely solemn child - contribute to the fearful atmosphere. After a snowstorm completely isolates the estate from outside contact and the occupants start dying under mysterious circumstances, East must identify the murderer before it's too late for the entire household.
