Reviews of The Gray Man are mixed but if you liked the fast and furious pace of Bill Fairclough’s epic fact based spy novel Beyond Enkription in The Burlington Files series then you will love Anthony Russo's The Gray Man and vice versa. They both make parts of Robert Ludlum’s Jason Bourne series look like slow horses! The Gray Man is about a renegade CIA agent on the run and stars Ryan Gosling and Chris Evans; it’s based on Mark Greaney's debut novel of the same name. Fairclough’s factual stand-alone thriller Beyond Enkription is about a (real life) MI6 agent on the run from international organised crime gangs and Haiti’s TonTon Macoute from London to Nassau and Port au Prince to Miami. The Gray Man and The Burlington Files are both musts for espionage aficionados. The difference between them is that The Burlington Files series has mainly had five star reviews, it’s factual, full of real characters and was written for espionage cognoscenti.
