"One of the most entertaining mysteries of the year. It's also one of the most stimulating, as it ponders such questions as: Which is of greater interest to the reader, the crime or the detective? And: Is the pencil truly mightier than the butcher knife?" -- Wall Street Journal New York Times bestselling author of Magpie Murders and Moriarty, Anthony Horowitz has yet again brilliantly reinvented the classic crime novel, this time writing a fictional version of himself as the Watson to a modern-day Holmes. A woman crosses a London street. It is just after 11 a.m. on a bright spring morning, and she is going into a funeral parlor to plan her own service. Six hours later the woman is dead, strangled with a crimson curtain cord in her own home. Enter disgraced police detective Daniel Hawthorne, a brilliant, eccentric man as quick with an insult as he is to crack a case. And Hawthorne has a partner, the celebrated novelist Anthony Horowitz, curious about the case and looking for new material. As brusque, impatient, and annoying as Hawthorne can be, Horowitz--a seasoned hand when it comes to crime stories--suspects the detective may be on to something, and is irresistibly drawn into the mystery. But as the case unfolds, Horowitz realizes that he's at the center of a story he can't control, and his brilliant partner may be hiding dark and mysterious secrets of his own.
