Campion visits the country house of the famous dancer Jimmy Sutane to investigate a string of unpleasant practical jokes, and falls in love. On Campion's first night at White Walls, another guest, Chloe Pye dies - though whether by accident, murder or suicide remains to be seen. Then there are more deaths, and Campion finds himself under pressure.

Influenced by his feelings for Linda Sutane, Campion refuses to believe the evidence against her husband Jimmy, and continues trying to clear his name. But when another murder occurs, Sutane's innocence becomes impossible to sustain.
