Chevenix believes he is being cheated by an architect, John Lake... and Mrs Chevenix claims that her spirit guide, an ancient Egyptian called Saphra, has warned her of an imminent death. There is a disputed will, a second unsigned will, the sound of shots behind locked doors, an apparent suicide which Poirot suspects is murder. Whatever you do, do not go out of the room during Dead Man's Mirror, or you will lose the plot!moreless
Poirot is caught up in a coup d'etat in Argentina and arrested as a spy, which hinders him from solving the murder of Iris Russell at a French restaurant owned by an Italian in Buenos Aires.
Two years later, in London, a dinner-party at a restaurant of the same name marks the second anniversary of Iris's death. The atmosphere is so charged that we almost expect the victim to come back from the dead. And, of course, Poirot traps a killer.
