Treason is a British spy thriller television miniseries created by Matt Charman for the streaming service Netflix.

The chief of MI6, Sir Martin Angelis, is hospitalised after being poisoned with a non-lethal dose administered in his whisky.

The book's titles and authors are a code that Adam deciphers that gives him the address and person he is to meet.

The website's consensus reads: "Treason may take itself too seriously but could deliver thrills to fans of the double-crossing espionage genre.

"[3] The Guardian described the series as a "gripping... fun, frenetic espionage thriller" but questioned its lead's hard-man credentials: "Cox is less an international man of mystery and more a lovely Labrador".

Not only does Cox utterly fail to convince as someone competent or ambitious enough to be made head of MI6 at 40, but the show insists on saddling him with endless cliché.
