Shirley Oliphant's dream is to take her grandkids on a picnic in a Rolls-Royce. Her husband, the old KO, finds just the car, a 1974 Rolls-Royce Silver Shadow once owned by a Mr Van Buren. Since his death, seven years ago, the Rolls has been sitting in Mr Van Buren's garage, keeping a secret. A deadly secret. And the old KO is about to discover that secret, and unleash it.
