While taking pictures at a society wedding, Kent Murdock stumbles upon a murder.
Every society family has skeletons in its closets, but only the Cannings have a fresh corpse. Kent Murdock finds the dead man while taking pictures at the wedding of Patricia Canning and Roger Armington, scions of Boston's most prominent — and camera-shy — families. Patricia and Murdock have been friends for years, and she invited him to photograph the wedding against her parents' wishes. For the killer, Murdock's appearance is very bad luck indeed.
The dead man turns out to be Patricia's ex-husband, whom she spent three days married to before the family pressured him into an annulment. He traveled to Boston in search of blackmail and found death instead. Whichever Canning killed him had hoped to sweep the murder under the rug. But Kent Murdock's camera has a way of finding the truth, no matter how ugly it may be.
