Harper lives in De Pijp, above a street that fills with market traffic every weekday morning. She has seen plenty of visitors come back from a day of shopping with more bags than energy, and she likes the booking that follows. Soapy and body to body are her usual formats, chosen by what the bathroom allows. English is her one working language, and she speaks it slowly and clearly for a guest whose own English is careful. At twenty-seven she has a teasing sense of humour and firm, clearly stated limits. If you name her in the first line of your message, the reply says whether she is free at your hour and, if she is not, who is, leaving the choice with you. Body to body with her builds gradually, with the oil warmed first and the contact increasing slowly rather than all at once. The balance is handed over when she arrives, by card or in cash, and cash in another major currency is fine once the exact sum has been confirmed in writing.

Harper 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.
