As a lonely and meaningless retirement beckons after 25 years on the force, the boys are given the task of finding 'The Black Widow' after a series of gruesome lonely hearts murders.

After mixing their drinks at the policemen's ball, Louis and Briggs confront a new horror involving a flasher, a Marquess and the commissioner's wife.

When forced to transfer into the Fine Arts Squad, our heroes are despatched to recover the latest artistic creation of 'enfant terrible' Hadyn Smailes - a pair of maracas, a tin of peaches and a fish tank of the artist's own urine.

When Briggs and Louis investigate an attack on a top figure skater, the pair wind up on ice but fail to gain marks for artistic interpretation.
