The Capture

BBC1, 9pm, Sunday & Monday

Seeing is no longer believing, viewers learned in series one of The Capture as DCI Rachel Carey (Holliday Grainger, right) uncovered a top-secret project at the highest levels of government to alter CCTV footage with undetectable sophistication.

Now Carey has joined the intelligence services, albeit at a frustratingly low level of security access, but soon she’s working with old colleagues again while investigating a bizarre murder.

Meanwhile, security minister Isaac Turner (charismatic Paapa Essiedu) has to decide whether to award a Chinese company a government contract for facial-recognition technology.

As the two storylines merge we glimpse a far-reaching conspiracy in which almost no one is who they seem to be. Writer Ben Chanan’s assured yarn is in the grand John Buchan tradition. ★★★★★
