12 Best Anthony Horowitz Books for Fans of Spy Novels

Are you ready for a new spy novel? Whether you’re looking to read an adult fiction work or one for young readers, try these 12 best Anthony Horowitz books.

If you are looking for the best book to read that will send you into a world of spies and mysteries, then you will want to look for one by Anthony Horowitz. This prolific author has been compared to Arthur Conan Doyle and Agatha Christie, two of the world’s most famous crime and detective writers.

He has written over 40 books, including the young adult series Alex Rider, the children’s book series the Diamond Brothers Detectives for Hire, and new books for both the Ian Fleming Estate and the Conan Doyle Estate to honor the style of their patriarchs.

Horowitz was born in 1955 in England, and from his early childhood, he knew he wanted to be a writer. He did not fit in well or work very hard in school but found reading to be his escape. He attended the University of York and studied literature before publishing his first book, The Sinister Secret of Frederick K. Bower, in 1979.

He had great success as a children’s writer and did not move into the adult literary world until the late 1990s. Today, he continues to write for audiences of all ages while composing screenplays for film and television.

7. Forever and a Day

This book is number two in the Horowitz Bond line but number 48 in the entire James Bond extended series.

“Bond had always had a loathing of opera; its absurdly large women, its histrionics, its noise. The fact that Larsen was spending his last night there was somehow fitting. He was on his way from one hell to another.”

“As far as I’m concerned, you can’t beat a good whodunnit: the twists and turns, the clues and the red herrings and then, finally, the satisfaction of having everything explained to you in a way that makes you kick yourself because you hadn’t seen it from the start.”
