Title: The Case of the Roving Rolls
Description: from the back cover:
When a snow-white vintage Rolls-Royce chases Jimmy Carson down the driveway of the Willoughby Estate *all by itself* -- well, as Jimmy would say, "Creeps!"  But that's only the beginning:  a strange hit-and-run accident, two quarts of sour cream, and a missing moustache start the incomparable Brains Benton and his partner Jimmy of on a truly international mystery as a kingdom hangs in the balance.
