H.B. Lyle’s An Irregular Spy Thriller series consists of four espionage novels published between 2017 and 2023. The series opens with The Irregular and continues through The Red Ribbon, The Year of the Gun, and Spy Hunter. Characters and storylines carry over from book to book, so reading them in publication order is the best approach.
The titles themselves hint at the kind of spy fiction Lyle writes, with names like The Year of the Gun and Spy Hunter pointing toward action-driven stories. The series came out at a fairly steady pace, with one or two years between most entries, though a three-year gap separated The Year of the Gun (2020) from Spy Hunter (2023).
Spy Hunter is the fourth and most recently published book in the series. Whether Lyle plans to continue beyond it remains to be seen, but four books give readers a solid run of espionage fiction to work through.
