Harper sets out from De Pijp, where the market streets go quiet after dark, and is twenty-seven, brunette and 170 cm. She works in English and has a dry, unhurried humour that settles a room quickly. Overnight bookings are among the lengths she accepts, and the house confirms one only after she has agreed to the dates and the address. Earlier in an evening she favours sensual oil, and what the session includes is settled by her before the oil comes out. An overnight with her is one eight hour block, half paid ahead, with its start and finish written into the thread, and it is easier to secure when asked for before the trip begins. From De Pijp she reaches hotels in the centre, along the Amstel or out in Zuidas inside the forty to sixty minute arrival window. On a shorter evening, sensual oil at ninety minutes or two hours gives her the pace she likes.

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.
