[1] Mix Cellini is a lonely, maladjusted young man who works for a company that repairs exercise equipment, and lives in the upstairs apartment of an old Victorian house on Notting Hill.

His reclusive elderly landlady, Gwendolen Chaucer, spends her time reading and pondering lost loves.

Mix, on the other hand, is obsessed with the serial killer John Christie, who had once lived nearby, and also with a local model, Nerissa Nash.

But the evening turns sour when Danila criticises his choice of 60s music, is revolted by a “cocktail” Mix has concocted, and makes derogatory remarks about Nerissa, after seeing framed photos of the model in the flat.

Mix wraps Danila’s corpse in plastic, and buries her beneath the floorboards of an empty room in the house.

Miss Chaucer finds Danila’s thong on her bedroom floor, where Mix inadvertently dropped it as he was moving the body.

As one of Miss Chaucer’s friends had seen Mix leaving armed with a knife, the police rush straight to Nerissa’s address.
