The main character, who works with computers in the day, dresses up as Audrey Hepburn at night, when he runs his unconventional nightclub. The mystery involves the murder of one of his nightclub employees, who had refused to turn over letters from a client that someone wants to use for blackmail.
Though the book is described as "outrageous and hilarious" and very popular in the author's native country, Turkey, I find much of the humor has been truly "lost in translation."
What may be excruciatingly funny in the original Arabic, culturally and linguistically, unfortunately didn't carry over for me into the English version. The "humorous" events fell flat. If you can, try reading the novel in the original!
Note: A "Teaser Tuesday" meme quote from the novel generated the comments for this post.
