Agatha Christie at Christmas: your complete guide to what's on when

There's a Miss Marple film starring Margaret Rutherford (AKA the one we all agree is nothing like Miss Marple)

There's Death on the Nile starring Peter Ustinov (AKA the one where the brilliant Angela Lansbury acts drunk the whole time)

And, of course, BBC1's brand-new two-part The Witness for the Prosecution (AKA the one we all hope will be as good as the one with Marlene Dietrich).

So, for all you amateur sleuths, here's the full timetable of murder and mayhem:
