Great UK cast, really sharp script and plausible characters, who all invoke various relevant emotions from the viewer (empathy, pity, contempt, frustration etc, depending on the character). Superb acting, with John Simm having a standout role that brings the best out in him (a change from the very wooden role he plays in"Grace"). However, not to unfairly single him out, the rest of the cast were all great in their differing roles. It had me in stitches on times and on the edge of my seat in others. Brilliantly intriguing whodunnit that'll keep you guessing past the final credits. It desperately needs a second series as there are certain character developments left incomplete, and if this doesn't happen I'll be bitterly disappointed, as I'm sure many others will. Loved it 👍🏻👏🏼
