Tango One Leather Stephen

A British crime thriller from Stephen Leather, one of the UK's most reliable voices in gritty undercover fiction. The story follows an elite undercover cop tasked with infiltrating a major drug cartel — but the deeper he goes, the harder it becomes to tell which side he's really on. Leather writes taut, procedural thrillers that feel ripped from actual case files, and this one delivers on tension and moral ambiguity. If you like your crime fiction procedural, British, and unafraid to show the toll undercover work takes on a person, this hits the mark. Pairs well with Andy McNab's Nick Stone series or early Robert Harris.
