Guests on a work trip tend to plan their free evening before they leave home, and they often plan it around her. Oud-Zuid is her base, close to the museum quarter. Every word of the evening will be in English, the one language she works in. She suits a guest who wants a calm, private hour after a day of meetings, and tantra or a sensual session is the usual request. She is twenty-six and dark-haired. Her limits, given on arrival, are final.

Olivia decides which bookings she takes and may decline any of them; she sets the limits for what a session includes, says what they are, and may end a visit at any point, as the terms set out.
