There are estimated to be a million undiscovered geniuses in the UK, and this show is out to find one. It’s a stressful, heartwarming, shocking watch – which raises big questions about the UK

This, then, is what Alan Carr did next. Fresh from his victory as the last traitor standing in The Celebrity Traitors, and elevation to national treasure status, the Chatty Man is co-presenting Secret Genius with Countdown’s dictionary-botherer, the lexicographer and author Susie Dent. On second thoughts, given the lead times for these things, this is probably better billed as “What Alan Carr was contracted to do next” but no matter. We are here to have fun and fun we shall! Though, this being a reality-competition show in which people take part in regional heats to find out who among them is “one of the estimated million undiscovered geniuses” in the UK (no definition of the term given – Dent, you had ONE JOB), it comes with a buffet of sob stories, a side order of stress and a hefty dollop of whatever the word is for that patented mix of schadenfreude and voyeurism on which the genre depends.

We begin with a dozen participants drawn from north-west England and Northern Ireland. They have either nominated themselves or – more often – been nominated by friends and family who know them as the cleverclogses of their circles. All will compete in the first round: eight will reach the second.

The first season aired 10 years ago – an entirely different world – so when it was announced that a second season was coming, my first thought was: oh no, lightning doesn’t strike twice. Delightfully, I was wrong.

If you haven’t revisited The Night Manager since 2016, here are the pertinent points: Jonathan Pine (Hiddleston), a night manager in a Cairo hotel, weaseled his way into the rarefied world of arms dealer Richard Onslow Roper (Hugh Laurie), AKA “the worst man in the world”, under the direction of Angela Burr (Olivia Colman), who ran a British intelligence operation. As a supposedly loyal henchman, Pine beguiled Roper, shtupped his girlfriend, imploded his arms deal and made off with a cool $300m, as Roper was dragged off screaming to a violent fate by unhappy customers.
