Everest

In the novel The Pale Horse, Zachariah Osbourne retired from his job as a pharmacist partway through the story and moved to Bournemouth. He named his new house on Glendower Close Everest.

He joked with the police that his house was where he took his "rest" and that he always liked the Himalayas and mountaineering.

However at the end of the case, Inspector Lejeune commented that the house name ought to have given Osborne's game away. The name was his little private joke, and Osborne delighted in such things. His business, after all, was to give certain people "Ever" "Rest", for the payment of a suitable fee.
