Poirot discovers the murder weapon, a sugar hammer, on open display at Long Meadows and accessible to all the suspects. In an attempt to flush out the murderer, Poirot claims to know more than he does, but when he is almost pushed under a train he uses a different tactic. He shows the four photographs at a party attended by most of the suspects, and Mrs. Upward reacts, so it seems, to the picture of Lily Gamboll. She refuses to say where she has seen the picture, though.
