Can You Keep a Secret?
9.30pm, BBC One
Dawn French continues to be a hoot as Debbie, a woman who’s pretending her husband has died for the insurance payout. But now the cat’s out of the bag: her police officer daughter-in-law Neha (Mandip Gill) knows that William (Mark Heap) is alive and demands they give the money back. Meanwhile, somebody else has worked out the scam and has used a very uninspiring font in a blackmail letter. But Debbie has zero intention of cowering to any threats. Great fun. Hollie Richardson
