Long legs, near-black brown hair, and 176 cm of slim frame that makes most rooms look slightly smaller. Stacy has brown eyes and the sort of face that photographs far better than it has any business doing. Early twenties. In Chelsea she dresses simply because she has to: at her height anything elaborate becomes a statement, so it is well cut trousers, flat shoes more often than not, and a coat that does the work.

Her English is unhurried and she is less confident than her height suggests, which is one of the more likeable things about her. She warms up steadily across an evening rather than arriving fully switched on. She swims, draws reasonably well, and keeps a running list of the Chelsea cafes that will let her sit for two hours over one coffee without hovering.

An SW1 evening with her is usually Colbert on Sloane Square, the corner brasserie with the pavement tables and the tiled floor, open early and late and entirely without ceremony. She likes an outside table and an omelette at an hour when other people are having dinner. She lives a few streets from the square, so the walk afterwards goes down Pavilion Road or along to the river, whichever suits the weather and the hour.

Dates from 12 October onward are the ones to ask about, since she is out of London until then. The Chelsea page has SW3 and the rest of the women there. An evening and a hotel in a message to booking will get you her first free night back.

Nothing has been written up under Stacy yet, which is usually what discretion looks like. A note goes on the board only when a client sends one in writing, she agrees to it, and the office has checked that it reads as a first name, a month and nothing private.
