On the slapstick side, but has its moments, this hearty humored adventure of Agnes and Andrew Kinghof who outscoop and outspoof their cousin, Lord Whitestone, of the Yard. There are two murders, a long lost brother and his sister, both couched in practical jokes involving a grinning pig's head. Everyone investigates -- or is investigated -- before Agnes lays aside her flair for madcap messes and helps Andrew close the case. Very British.
