Like any good mystery, Anthony Horowitz's "A Line to Kill" has a gripping story, quirky characters who might be devious or might be innocent, a twisty plot, an enigmatic detective and a memorable setting.
But it also has something else: sly humor, most of it at the expense of the author.
"A Line to Kill" is the third in a series of mysteries that feature Horowitz as himself — or, more precisely, as an exaggerated, comic version of himself.
Horowitz is a bestselling British author, creator of the BBC television shows "Foyle's War" and "Midsomer Murders" and the author of the popular Alex Rider novels for teens.
The fictionalized Horowitz is all of those things — as well as a little pompous, a little overly confident, a little vain and wholly unable to solve any mystery despite having written dozens of them. He also has a lot of trouble keeping his mouth shut.
The enigmatic detective is a man named Daniel Hawthorne, a former detective inspector who left the force under murky circumstances — a known pedophile he was questioning fell down a flight of stairs (or was he pushed?) and was badly injured. But Hawthorne is brilliant and can solve crimes nobody else can crack, and he's in great demand as a private investigator.
In the first book in this series, "The Word Is Murder," Hawthorne suggested that Horowitz (whom he calls "Tony," perhaps innocently, perhaps to needle him) shadow him while he investigates a murder and then write a book about it; they would split the proceeds. This was the premise for the second book, as well, "The Sentence Is Death."
In "A Line to Kill" both men are invited to a writers festival on Alderney, one of the Channel Islands off the coast of England, despite the fact that Horowitz is way behind schedule with his manuscript and they have no book to promote.
