Canadian Author of the George Ryan Archaeological Thrillers

Welcome to the official website of Cathal Flynn-Post, author of the George ‘Seoirse’ Ryan Archaeological Thrillers Series. Discover archaeological mysteries inspired by real history, breathtaking locations, and years of on-location research across Canada, Ireland, Scotland, Peru, and beyond.

His curiosity rarely switches off. A weathered ruin, a local legend, or a chance conversation can become the beginning of a new mystery. He is especially drawn to the gaps in the historical record, the moments where fact gives way to possibility and a single unanswered question can open the door to an entire story.

Ideas often begin during his travels, sparked by a landscape, an overlooked detail, or a story shared by someone who knows the area well. From there, he begins exploring how real history might support a fictional mystery and what could be waiting beneath the accepted version of events. For Cathal, the most compelling adventures begin where documented history ends and the unanswered questions take over.
