Davy calls Miss Marple and Pennyfather back to London. She is in her room and he enacts his likely movements when she saw him in the hallway. She realises she saw a younger man, though with Pennyfather's appearance, and recalls the German term "doppelganger". This jogs Pennyfather's memory; he remembers he saw "himself" sitting on a chair in his own hotel room, just before he was knocked unconscious. The criminal gang was counting on his absence, and reacted violently on his appearance.
