One by one, the guests begin dying off. Mike Raven chokes after taking a drink and dies, and a small Indian figurine from the centerpiece tray is broken away. In the morning, the tram cable is cut, killing the cook, Mrs. Grohmann, who attempted to escape. General Mandrake conducts a search of the chalet's catacombs, splitting everyone into pairs, ultimately leading to his demise, stabbed after being led to a planted distraction (a cat). It becomes clear that their unseen killer is following the nursery rhyme. Ann Clyde, the secretary, enters into a romantic relationship with engineer Hugh Lombard as they and the others begin a deadly cat-and-mouse game, ultimately deducing that Owen is not their host but, in reality, one of them.
