Lois Meade is boss of a cleaning business, and finds time
on the side to indulge her love of sleuthing. She opens an
office in nearby Tresham, and is intrigued to see a number
of surprising visitors to the small shop on the other side
of the street. Their window display tells all! New business
comes her way when she is asked to clean the house of
Tresham`s pompous and secretive mayor, Howard Jenkinson. A
locked room arouses Lois`s curiosity, especially when the
mayor`s chauffeur is seen collecting a parcel from the shop
opposite. Lois, her daughter, and some of her regular
cleaners, gradually uncover lies, adultery and sex for
sale. When seemingly harmless goings-on result in death and
murder, it is time for her old admirer, Inspector Hunter
Cowgill, to become involved. True to form, Lois ignores his
warnings and finds her own life in danger.
