"Actor Toby Flood, formerly of big and small screen but now seldom seen on either, arrives in Brighton on tour. Flood is visited that night by his estranged wife, Jenny, now living with wealthy entrepreneur Roger Colborn. Jenny runs a shop in the Lanes and is worried about a strange man who is hanging around outside. Roger has dismissed her concerns but Jenny persuades Toby to do something. The next day Flood trails the man and confronts him. Derek Oswin is an unemployed loner who blames Roger Colborn for his father's death from cancer on account of dangerous practices at the now-closed plastics factory run by Roger and his late father, Sir Walter Colborn. However, Oswin is a fan of Flood's and eventually he agrees to lay off. Then, Colborn gets wind of Flood's contact with Jenny and tries to buy him off, but Flood sees only a longed-for opportunity to win Jenny back, and continues to investigate the death of Sir Walter, seven years ago." -- Provided by publisher.
