Kati is fed up. Her rent has been put up again. And although her apartment is in a lively area of Istanbul, the neighbourhood is definitely run-down. And she is fed up with her boyfriend, Selim, as well – he actually expects her to behave like the future wife of a lawyer and politely engage in small talk. To move in with Selim is thus out of the question. She would prefer to find out how to bribe the authorities in order to come by a flat of her own. At first, it all goes like clockwork: an official offers her a six-room apartment overlooking the old town and the Bosporus at an unbelievably cheap rent. The fact that the flat is in need of some renovation is of no concern to Kati – she learned in Berlin how to spruce up an apartment. In the event, however, bribery and a spot of renovation are not the end of the story. Shortly after her visit, a man is murdered inside this dream apartment – a parking-lot manager with a dubious reputation. A nuisance for the future owner of the apartment – not least because she herself is one of the suspects – but a challenge for that shrewd owner of a crime novel bookshop, Kati Hirschel.
