Treason

I was nearly swayed by reviews not to watch this latest offering in a season of good spy yarns - what a mistake that would have been.

Sure it has a handful of procedural errors, but Treason is a very good story nonetheless and won't disappoint people who love this kind of show.

Mostly set in London, and boasting a good international cast, Treason will keep you guessing - its intrigue only slightly diminished when it becomes clear who the final traitor is. But like most good spy yarns there's more to it than simply resting on the shoulders of a whodunnit - how the chips fall at the end is equally as important.

A good holiday binge that should keep viewers entertained.
