Poirot reveals that the real murderer is Nick. Michael was engaged to Maggie, not Nick: the cousins have the same name, Magdala Buckley. After learning of Michael's wealth and disappearance, Nick plotted to present herself as Michael's fiancée to usurp his wealth, a plot which required Maggie's death. The attempts on her life were her own work. George used to supply cocaine to both Freddie and Nick concealed in wristwatches; Nick used her supply to poison the chocolates. Nick is arrested, taking Freddie's wristwatch as a "souvenir"; the full box contains enough for Nick to take an overdose and escape the gallows. Poirot tells George either to surrender himself or go away, allowing Freddie to recover from her addiction. In the end, Jim and Freddie decide to marry, and Jim, who is an art dealer, reveals to Poirot that one of Nick's paintings on the wall is actually worth a fortune, though Nick herself did not realize it.
