The Vows of Silence — Susan Hill

Melanie shops happily for supper the day after her return from honeymoon but when she gets back from the supermarket there is someone other than her new husband waiting for her. . . .

Tanya and Dan, who have been married that day, slip back into town to enjoy the fun of Lafferton's 'Jug' Fair. Also in the throng among the roundabouts and coconut shies are middle-aged Helen and Phil who are planning their wedding. And someone else. Someone bent on destroying happiness -- and lives.

Simon Serrailler is faced with a number of apparently motiveless murders. Could the link be love and marriage?
