Sounds good! If you like lengthy Russian novels, especially the ones about the Tsar period, AND, you also like prostitutes with whom you can talk about various deeper subjects, there is always "Crime and Punishment" by Dostoyevsky: it is long, Russian, set during the period of Tsarism, and has a prostitute as one of the main female characters . Fits the bill fine, right?

Good luck - I am sure you will do fine. The Dutch-speakng prostitutes sound like good chums for you.
