When Mary Fisher, a mystery bookshop owner, receives a call from her friend Henry, inviting her over to see his new classic car, she immediately accepts. But Henry's "new" car--a 1955 Buick Century--puts him in danger. An intruder attacks him in his garage, and Mary hears the scuffle. With Henry in a coma, it's up to Mary to find out who hurt Henry, and why. Henry's twin daughters are at his side in the hospital, so Mary puts her analytical mind to work to help him in the only way she knows how. But the man Henry bought the car from has vanished, and someone is following her around Ivy Bay.
