Four blonde escorts, one entry each: honey to caramel, no shade repeated

The four, entered in turn

Cindy stands 168 cm, slim, with blue eyes. She practises yoga, sails when the wind allows and rarely goes out without a camera, and she is relaxed enough to make a first meeting seem unplanned. Her diary favours daytime and early evening, so a late lunch followed by an hour in Green Park plays to it.

Nancy is 170 cm with blue eyes and a curvy figure, and she has recently turned thirty. She swims, likes a long drive out of town and has a weakness for sushi. Her weekends are the part of the diary to ask about first.

Nora is 166 cm, athletic, with hazel eyes and a spirited manner. Fashion design is her real interest, followed closely by champagne and an early hour at a flower market. She would rather have a day's notice than an hour's, and an afternoon along Bond Street gives her eye for cut something to do before dinner.

Thea is 165 cm with green eyes and a curvy figure, and she is happiest outdoors. She hikes, cycles and orders Japanese food with authority, so a table at Umu on Bruton Place is an easy evening to arrange. Given the choice, she will walk across Hyde Park rather than take a cab.

Matching the companion to the evening

For daylight hours, begin with Cindy. For a four hour dinner at £900 that should close with a nightcap rather than a clock, Nancy or Thea. For an evening with a shopping hour or a gallery at its front, Nora. For a weekend away, write early with the dates: the weekends and extended stays format is priced per request and comes back as one written figure covering the whole stay.

If two of the four appeal equally, name both in the message. The reply says which of them is free at the hour you want, so the choice is settled by the diary rather than by a second look at the photographs.

Where the four set out from

None of the four lives inside W1. Cindy is based in Chelsea, Nancy in Covent Garden, Nora in Paddington and Thea in South Kensington, and each reaches a hotel on Park Lane or Grosvenor Square without difficulty. Distance never moves the figure: travel anywhere in Zones 1 and 2 is inside it, so a guest on Carlos Place pays exactly what a guest beside Paddington station pays.

How the shade is checked

Hair colour is the detail a photograph flatters most easily. Before a record is published the house sets each portrait beside the woman herself, so the shade on the card is the shade that crosses the lobby. Should she change her colour later, the record is checked again.

Cross references

Nancy and Thea are also filed as curvaceous. Cindy appears among the slim and slender, and Nora among the toned and athletic. By age, Cindy, Nora and Thea sit in late twenties, and Nancy in thirties and beyond.

Writing to the house

Put the companion's name, the date, the hour and the hotel into a single WhatsApp or Telegram message. What comes back is a written confirmation of her and of the figure. That same figure is handed to her in person on the night, and it never grows between the reply and the door.
