Victoria Treadwell, dispatcher for the sheriff's office, is driving to work in a snowstorm when she sees a car fish-tailing behind her. Horrified, she watches at the car swerves off the road. When she heads back to help, she finds the driver bent over the steering wheel and barely breathing. In the back seat is a tiny child in a pink snowsuit. Victoria calls for an ambulance and then dials her boss, Pete Manstead, Undersheriff, of Charlevoix County. The ambulance arrives and the paramedic tries to shock the woman's heart back into rhythm, but the driver, who they learn is named Carly Yellowwood, is dead. From the autopsy, Pete finds Carly died of a drug overdose, although she didn't use drugs. The coroner lists the cause of death as murder. Pete sends his deputies to visit Carly's neighbors and learns she has been seeing two men. One is her ex-husband, Joe Yellowwood, a Native American living on the nearby reservation. No one knows the second man. Since Carly Yellowwood was divorced and has a new boyfriend. Pete believes its a crime of passion. Victoria, who hopes to adopt Carly's motherless child, thinks the motive is far darker.
