You wouldn’t expect a drama called Dublin Murders (BBC One) to be a laugh a minute, but the cumulative anguish, menace and torment of this eight-parter made it almost unbearable, even if viewers were thrown a tiny scrap of hope in the final frames.

This series examines murders in the USA “with elements of love and passion as well as prejudice”, and the second season opened (on BBC One) with "Killing in the Classroom", the story of the fatal stabbing of New York school student Matthew McCree by bisexual teenager Abel Cedeno.

What did we learn at the end of The Capture (BBC One)? A rice jar is a good place to hide USB sticks. It’s possible to withhold the opening credits for 11 whole minutes. A green coat works exceptionally well with light blue eyes and shoulder-length auburn hair.
