It doesn’t take Clare Hunter many years of married life to discover that her husband, Arnold, is ruthless and unscrupulous. But it is not until she attempts to break up their unsatisfactory marriage that she herself becomes victim of his power-complex.

To prevent her leaving him, Arnold resorts to blackmail-of a highly specialised variety. Ordinary legal methods seem powerless to cope with the situation and Clare is becoming desperate when she finds an ally in a former colleague, Hugh Cameron. With little to guide them but their own ingenuity, these two can only rely on each other.
