In the short story The Capture of Cerberus, Hell is a nightclub in London. When Poirot meets the Countess Vera Rossakoff who asks him to meet her in “Hell”, he does not understand what she means. Miss Lemon however, knows all about it. According to her, it is a nightclub, supposedly newly set up by a Russian woman and very trendy. Miss Lemon makes a reservation for Poirot and he goes there and finds the place decorated appropriately--stairs leading down to the place are painted with phrases, the "good intentions that pave the way to hell". The entrance requires the crossing of a water feature and the door is guarded by a large black dog named Cerberus.
As the text reveals, the telephone number of the nightclub is Temple Bar 14578 and the address is 13 End Street, WC1.
Interior of the nightclub[]
Archaeologist Professor Liskeard had been involved with the interior design of the nightclub.
When entering the club, patrons descended a flight of stairs. At the bottom of the stairs was a tank of water, with scarlet lilies. A boat shaped bridge crossed the water. On the left side was a marble grotto with a large black dog.
The walls in the club proper were decorated with frescos. One fresco depicted Orpheus and a jazz band, while Eurydice was glancing hopefully towards the grill. On the opposite wall was another fresco. This one showed Osiris and Isis throwing an Egyptian underworld boating party. The painting on a third wall was of a group of bright young people enjoying mixed bathing in a state of Nature. The contests described it as the Country of the Young.
