Constance lives in Oud-Zuid, near the concert halls and theatres that let out at around the same hour each night. She speaks French, Dutch and English, and her replies are unhurried. At thirty she has a clear sense of what an evening can carry, and she prefers tantra and sensual work to anything brisk. Her limits are named at the door and kept there. A guest who has left the foyer, reached his room and silenced his phone is the guest she expects.

Constance 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.
