The novel in which the historical fabric of Istanbul plays a major role, is about a chase full of interesting characters and mysterious clues, and is likely to become  a modern detective story classic for children. Gülsevin Kıral, with her simple language and great narration, tells eleven year old Mustafa’s efforts to solve a case while trying to impress  Elif.


Everything starts with the ad in a newspaper- “Detective’s Assistant Wanted”.During the summer, Mustafa works in the  office of detective Ömer Hepçözer, his father’s former policeman friend. He immediately finds himself in the middle of an adventure. Something strange is happening to the major monuments in Istanbul. Some thieves seem to have incredible plans on ….the city itself!
