Anthony Horowitz is a very famous author and screenwriter whom I don’t recall ever hearing of before. (Though he created both Midsomer Murders and Foyle’s War.) I got a chance to read The Twist of A Knife, book 4 in his Hawthorne and Horowitz series, and found it distinctive, well-crafted, and entertaining. Also a little weird. Which isn’t necessarily a bad thing.

In this series, apparently, author Horowitz has cast his real-life self as the narrator. References to his own life seem to be authentic (I have no way of checking). But here he has invented a situation (I assume it’s fictional) where he’s gotten involved with an enigmatic private eye known only as Hawthorne. They solve cases together, and Horowitz turns them into bestselling books. Hawthorne appears to be somewhat autistic. Certainly peculiar. He was kicked off the police force, lives in a sterile flat, and never talks about his life. He keeps his own counsel entirely, and Horowitz can never tell what he’s thinking. He’s not above petty revenge when he feels insulted. There are echoes of Holmes and Watson here, but Hawthorne is Holmesian in a highly distilled form.

As The Twist of a Knife opens, Horowitz is telling Hawthorne that he wants to end their association. The books they’ve produced have done well, but it’s all been too intense for him. He wants to go back to his quiet life of ordinary writing. Anyway, his first West End play is about to open. He hopes this will be the beginning of a stellar playwrighting career, a new stage in his life.

The first night seems to go well. But critic Margaret Throsby is in the audience – the most hated critic in London. She appears at the first night party and insults the cast, and then writes a scathing review. Soon after that, she’s dead – stabbed to death with a dagger which happens to belong to Anthony Horowitz. The police question him, and he suddenly finds himself in personal need of Hawthorne’s detective skills – but will Hawthorne be willing to help?

The tone is generally light, though the dramatic tension is elevated enough. Horowitz is not a great prose stylist, and his characterizations are (in my opinion) a little superficial. But the plot was extremely neat and clever. The book succeeds primarily on the author’s inventiveness, and that is formidable.

The author also deserves credit for venturing into the dangerous territory of discussing race and “cultural appropriation.” He does it in a safe way, by making the minority concerned one whose actual presence in England is negligible, but I think he was brave to address it at all.

The classic Agatha Christie “payoff” scene was artfully done. There was even a positive Narnia reference.

The Twist of a Knife is a professionally crafted detective entertainment that will particularly delight fans of the Cozy subgenre. Worth the price for the entertainment.
