Frank is engaged by solicitor Faulkner who is representing a local hotel. A young woman, Miss O'Hara, has complained of contracting food poisoning from mushrooms she ate there and is threatening to sue and go to the press with her complaints. He believes her claim is bogus and wants Frank to get the evidence.
Towards this end a trap is set up. Miss O'Hara is asked to visit a Doctor Skerrett at Knowle for a second opinion. She does so and he cannot prove or disprove her claims. Frank though now comes centre stage. Bus services from the village are infrequent so the woman has to wait at the local pub. While there Frank seeks her out posing as a friendly and very generous travelling salesman. With great aplomb he breaks the ice with her and more than wins her confidence. He invites her to eat with him and she not only does she accept but has mushrooms as well. Faulkner is present to see her suitably exposed and she is offered ten pounds to drop her claim and avoid charges herself.
