Informer's Gabe may have bitten off more than he can chew as the tense drama concludes

The secret undercover activities of reluctant counterterrorism informer Raza (Nabhaan Rizwan) have devastating consequences for his family in this excellent drama’s final episode.

Raza’s own life is in danger when, to the horror of his police handler Gabe (Paddy Considine, pictured above with Jessica Raine’s Emily), Raza’s successful infiltration of the east London terrorist cell brings him much closer to the terrorism mastermind than anyone had envisaged.
