Dr. Leidner, an archeologist on a dig in Iraq, hires nurse Leatheran to attend to his wife. Mrs. Leidner has “fancies”. She’s terribly afraid of her former husband, a man convicted of being a German spy in the war and thought to be dead, but she’s lately been the recipient of threatening letters from him. One afternoon, Mrs. Leidner is found with her skull crushed in in her bedroom. No one could have entered or left the compound. It had to have been one of the archeologists on staff.
Again, following the Christie pattern, we’re invited to suspect Father Lavigny, the epigraphist. He is indeed an imposter and he’s there with no good intent, but he’s not the murderer. There’s too much against him.
Why did Leidner hire a nurse for his wife? And not one trained in mental cases, an ordinary hospital nurse? He gives a kind of explanation to Poirot, but it’s the kind that explains nothing. Only three men have alibis. Two were away from the compound and numerous people swear Leidner never left his work on the roof.
I knew which way I was leaning when the paper Anne Johnson finds clinched it. The letters to Mrs. Leidner were in her own handwriting or something very near it. What Johnson found was evidently Dr. Leidner’s rough draft of one. It’s just a matter of how, and again, Johnson tells us that just before she, herself, is murdered: the window. Leidner didn’t have to leave the roof. He coaxed his wife to look out the window then dropped a heavy stone on her head. He hired a nurse to prove his alibi. When she saw the body, she would know how long it had been dead, and all knew that Leidner was on the roof at that time.
The why was less clear and the explanation is incredible. He was her former husband escaped from prison and death, who over the course of twenty years was so changed that Mrs. Leidner didn’t recognize him anymore.
