Dead Man's Mirror

At an auction, Hercule Poirot wants to buy an old looking glass. An art dealer called Gervase Chevenix outbids him for it, but the dealer then offers Poirot the mirror if he will investigate a mystery for him. 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.
