There's a Sherlockian Double Bill for Christmas eve (from 9pm, BBC 2) as #killingsherlock reaches a ghostly conclusion - thanks to a star turn from Ted Lasso's Nick Mohammed. Then Mark Gatiss dramatizes the Conan Doyle ghost story - Lot no. 249. Thanks to my lovely wee Ep 3 team @RebeccaLee @LilyBell @LeahMonteiro - who discovered Nick Mohammed's interest in Houdini & Doyle and single handedly persuaded him to take part! Happy Christmas everyone - may next year bring better tele tidings.
