A Line To Kill
When Ex-Detective Inspector Daniel Hawthorne and his sidekick, author Anthony Horowitz, are invited to an exclusive literary festival on Alderney, an idyllic island off the south coast of England, they don’t expect to find themselves in the middle of murder investigation—or to be trapped with a cold-blooded killer in a remote place with a murky, haunted past.
Arriving on Alderney, Hawthorne and Horowitz soon meet the festival’s other guests—an eccentric gathering that includes a bestselling children’s author, a French poet, a TV chef turned cookbook author, a blind psychic, and a war historian—along with a group of ornery locals embroiled in an escalating feud over a disruptive power line.
When a local grandee is found dead under mysterious circumstances, Hawthorne and Horowitz become embroiled in the case. The island is locked down, no one is allowed on or off, and it soon becomes horribly clear that a murderer lurks in their midst. But who?
Both a brilliant satire on the world of books and writers and an immensely enjoyable locked-room mystery, A Line to Kill is a triumph—a riddle of a story full of brilliant misdirection, beautifully set-out clues, and diabolically clever denouements.

Anthony Horowitz
Long before Alex Rider became a teenage icon or Sherlock Holmes returned to the page with fresh intrigue, Anthony Horowitz was crafting mysteries of his own—first in his imagination, then on the page. Born in 1955 in Middlesex, England, Horowitz grew up surrounded by stories, both real and invented. He discovered early that fiction was more than escape; it was a place to find order in chaos, to solve puzzles that real life couldn’t.
What sets Horowitz apart in the world of crime and thriller fiction is not just the breadth of his work, but the way he reinvents the familiar. Whether he’s breathing new life into Conan Doyle’s beloved detective or twisting timelines in Magpie Murders, Horowitz writes with a sleight of hand that keeps readers constantly guessing—and always a step behind. His novels don’t simply offer whodunits; they explore the act of storytelling itself, often blurring the line between author and character, fiction and reality.
Hawthorne and Horowitz Investigate
In a genre obsessed with control, here’s a mystery series that thrives on unpredictability—even for its narrator.
The Hawthorne and Horowitz Investigate novels crack open the traditional detective story and rearrange the pieces with sly wit and unnerving precision. At the center is Daniel Hawthorne, a former detective with a genius for deduction and a habit of keeping everyone—especially his biographer—in the dark. That biographer? A fictionalized version of the author himself, reluctantly dragged into real-life murder cases and quickly realizing that writing the story is nothing compared to living inside it.
Hawthorne and Horowitz Investigate consists of six books and series is set to expand with the upcoming release of one more book. The current recommended reading order for the series is provided below.
