Overcast Sunday is set in April 1950 in Wellington, the capital of New Zealand. It describes events that occur over a twenty-four-hour period after a young woman is discovered murdered in an inner city alley outside the Greek Club. The Police, already having a similar unsolved murder on their books, are keen to make quick progress and apprehend the killer to avert panic. The prime suspect is Jimmy, a veteran of Abyssinia, Dunkirk, Greece and Crete, who works as a chef in a local hotel. He is also a champion ballroom dancer and has a reputation as a ladies' man.
