Florence Shaw

Nurse Florence Shaw is worried about her patient and friend, elderly widow Nora Selleck. When she encounters Nora in the market town of Stone seeming confused, Florence decides to pay her a visit in more familiar surroundings. But at Nora's house she meets Ben Evans, a mysterious young stranger who has befriended Nora. Who is Ben, and why is he encouraging Nora to miss her surgery appointments? Florence doesn't trust Ben. She's sure he doesn't have Nora's best interests at heart and is a threat to her vulnerable patient.

Richard and Christine Clay have been married for decades. Their relationship has stood the test of time despite Christine appearing passive while her husband is unmistakably dominant - at times bullying and controlling. Nurse Florence Shaw has seen Christine at the surgery a number of times with minor complaints over the past year, none of which has led to a serious diagnosis. But when Florence hears that the couple appear to have entered into a suicide pact, she is shocked, though not surprised that Richard has survived.
