Albert Wilson witnesses how Peter Roberts is hit by a hit-an-run car. Wilson is sure it was no accident and is able to give a full description of the car. It belongs to Derek Wallis, who claims that it was stolen. He also has an alibi which is corroborated by his employer Elsa Jenner, but Albert Wilson is almost positive that it was Wallis, who drove the car. Aunt Peggy "happens to come across" a lot of cheap cigarettes, but they seem to contain something with a little more kick than ordinary tobacco. The cigarettes also come from different supplier and he wants them back - badly!

The police suspects Ken Dekin of illegal gambling. But somebody else is after Dekin as well. It may be his wife because he is about to leave her for a younger woman, but former employees may also have a grudge against him. Cupid is busy shooting arrows at PC Walker and nurse Cassidy. This does not suit DS Dawson who was his sweetheart at the police academy and still cherishes the handsome constable. David reads an article about Hugh Hefner in a magazine left by one of his passengers in the taxi and decides to get a den like Hefner's, especially where he can be left alone by Aunt Peggy. Needless to say, she does not like that at all!
