Los que aman odian

Middle aged Homeopath Francella takes the train to the hotel run by his sister in the treeless Bosque de Mar dunes only to find that femme fatale Luisana Lopilato and her entourage are already in residence.

There's some style to this one, with the forties detail (celluloid frame glasses prominent) and restricted palette (Digital Cinecolor). They cite McCoy, Goodis and Hammet but the large dose of perversity signals Agatha Christie, along with the string of close-ups telling us the characters are going to be suspects. When the murder does come, the investigation is protracted, killing off whatever momentum the scene setting has provided.

Definite curiosity value however.
