But what identity has the villain taken? Among the guests, Poirot not only finds the bedridden Katrina, but also her imperious Austrian psychotherapist Dr Lutz, M.P. Run by the hearty (yet corrupt) Italian Francesco, the hotel is world-famous for its Alpine spa treatments, and much to Poirot's surprise, it is also Marrascaud's current hideout. Pitying the man, Poirot agrees to reunite the lovers pro bono and sets off to the Hotel Olympos in Rochers Neiges, Switzerland, where Katrina is supposedly staying. Three months after Lucinda's murder, a lonely chauffeur asks Poirot to find his true love, the maid of celebrated Russian ballerina Katrina Samoushenka. The catastrophe weights heavily on Poirot's conscience, and he sinks into a steady depression, despite the entreaties of his physician, Dr Burton. A confident Poirot is convinced the criminal will be apprehended, but he does not foresee the eventual, disastrous outcome: not only does Marrascaud pinch the painting, but Lucinda herself is brutally murdered, and her jewels are stolen as well. In an attempt to snare the enigmatic art thief Marrascaud, Poirot and the Metropolitan Police set an irresistible trap: at the society debut of wealthy aristocrat Lucinda Le Mesurier, a priceless painting called 'Hercules Vanquishing the Hydra' by Marrascaud's favorite artist will be displayed, with Lucinda wearing exquisite diamond jewelery.
