The protagonist in the novel is a photographer living alone in Istanbul. One day he notices a bruise on his shoulder. A deep purple mark… When the marks multiply and begin to spread all over his body, he visits the doctor and learns that they are his own teethmarks. We have before us an obsessive artist, worrying himself to death and suspecting that his thoughts are being read. The novel begins with a young man who lives alone in Istanbul falling asleep one night in a municipal bus. He is woken up by the driver at the last stop. In an odd district that is foreign to him in every way… That night he is forced to stay there. When he has returned to his regular life, nothing continues as it was before. This is because the next day he comes across a mark on his shoulder. A bruise… And these marks begin to multiply. They spread over his whole body. When he learns that the only person responsible for the marks is himself, his life turns into a nightmare. The past and the present moment, fed by some common details and people, begin to become intermingled. His being becomes riddled with the obsession that his thoughts are being read and with the frustration of not being able to find a subject for his first one-man exhibition. The protagonist lives with the dream of becoming a renowned photographer. However, his days are spent taking passport photos in his small studio in an overpowering shopping centre. From time to time he takes part in minor exhibitions with a few photographs. In his past, which we read as a kind of parallel life, however, there is a younger man whose dream is to open a photography studio in Istanbul, but does only wedding photography in the ballroom of a seedy hotel. His youth, cooped up in the hotel’s personnel room, is afraid of always staying there while his self who has escaped from there is afraid of being unable to get out of the life he is leading. Rather than reading about the life of a man, we witness the identity crisis and paranoia of a man who confuses the life he desires, the life he lives and the life he shuns. Dark Room gradually envelops the protagonist both as a place of creation and as a metaphor for the fear of non-creativity. To discover the secret of the marks that continue to multiply, he decides to go to the district where he thinks everything began. He knows how to get there. Getting on the same bus and falling asleep…
