Born in 1969 in White Plains, New York, John Altman has lived in Colorado, New York, Massachusetts, and New Jersey. He graduated from Harvard University in 1992.
A Gathering of Spies, John's debut novel, came out in 2000; Publishers Weekly called it ‘an irresistible page-turner from a welcome new voice in the genre’. Since then he has brought alive international intrigue from the early days of World War II (‘John Altman proves himself worthy of the highest ranks in the espionage genre’, Barnes & Noble on A Game of Spies), through Eisenhower’s postwar America (‘Violent, suspenseful, fast-paced, and chockablock with unexpected twists’, Booklist on The Art of the Devil), to the Code Orange age of the ‘War Against Terror’ (‘Forget the competition for Thriller of the Year; John Altman has already won it’, St. Louis Post-Dispatch on The Watchmen). His latest, Disposable Asset, takes place against the backdrop of ongoing brinksmanship with Putin’s Russia. ('This can't-put-it-down spy thriller introduces the most deadly and proficient young woman warrior since the Hunger Games' Katniss Everdeen': Publishers Weekly, starred review.)
In addition to writing fiction, he has worked as a teacher, musician, and freelance writer. His thrillers have sold over a quarter-million copies in the United States, the United Kingdom, Italy, Japan, Poland, and the Netherlands. He lives with his wife and children in Princeton, New Jersey, where he is at work on his next book.
