In this the third Istanbul Murder Mystery novel, Kati, the owner of Istanbul's only mystery book store, once again gets involved in a case that is none of her business. Every day, a beautiful woman lunches alone in the restaurant next to the bookstore. When the woman is found dead in her apartment, Kati immediately recognises the stranger from the restaurant in images in the newspaper photos. Although the police believe it was an accident, Kati suspects something more sinister has happened, and sets about proving it.
