Coming March 27. ack Taylor (Iain Glen, Game of Thrones, Downton Abbey) is a former cop turned private investigator with little to show for his time in the Irish Guards but his old police overcoat. Few of his former colleagues have any regard for Taylor, who looks more like the people they arrest every day than one of their own. Based on the bestselling crime novels by Ken Bruen, this gripping drama has been hailed as "brilliant" (The People, UK) and "impressive" (Daily Mail).
