When Martin Trent rings home to announce his return from abroad, Susan is filled with fear - a fear based on what has happened before, and her dread of further violence. On the way back from the station to Bishop St Leon, Martin demands to be dropped at the local pub. Leaving after closing time, he is furious to discover that Susan is not outside, and when he gets home he makes his anger clear.
Why does Susan put up with this treatment? She never mentions it, though neighbours suspect what is going on. Then Adam Wilson rents a room in the village: describing himself as a researcher, he carefully acquires information about the Trents without revealing his interest. Meanwhile, police officer Roger is becoming anxious about Susan's safety. But before anyone moves to protect her, the horrific truth about the relationship between Susan and Martin is exposed . . .
