Introduction

Pretty young university students Rose and Poppy Matheson are keen golfers. But one night Poppy is attacked on the footpath near the golf course and her sister, following behind, mistakenly kills the attacker in trying to rescue her twin.

The Cover-up

The girls cover up the crime by making it look like a hit and run car accident, but are overheard by another golf club member, Betty Russell, who wants to go to the police. Unfortunately her husband dissuades her and starts blackmailing the girls instead.

Investigation and Disappearances

As Inspector Govern and Sergeant Beck try to disprove the hit and run theory, first Betty, then her husband Barry also disappear. Meanwhile Rose's boyfriend John cannot understand why her manner towards him has changed. For her part Rose still loves him but is overwhelmed with guilt.

Resolution

And it is not until after the discovery of two more dead bodies that all can be resolved.
