H.B. Lyle writes espionage and thriller fiction, with all four published books belonging to the An Irregular Spy Thriller series. The series started with The Irregular in 2017 and has continued through Spy Hunter in 2023, with books arriving every couple of years.

The titles suggest a world of spies and covert operations, and the gaps between releases (2017, 2018, 2020, 2023) point to a deliberate writing pace rather than a rapid-fire approach. With four entries so far, this is a compact series for readers who want a spy thriller they can work through without a massive time commitment.
