Like Cabot Cove in Maine, USA, St.Mary Mead in Great Britain seems to be the murder capital of that country. You would think so with Miss Marple solving all those murders in and around there.

The murder victim in this case is a very nasty sort of man who has the title colonel from his army days. Robert Lang is a nasty version of that satirical figure from the United Kingdom between the wars Colonel Blimp. his guy expects his family to address him as Colonel and they do. He's pretty disliked by one and all.

Reverend Paul Eddington finds Lang slumped over his (Eddington's) desk at the vicarage. There's a long list of suspects.

What the two who planned it also planned to use Jane Marple as an alibi witness as they know she's outside tending her garden at the time planned. Both make sure Joan Hickson sees them. It's what throws off both Scotland Yard as Miss Marple.

Hickson comes pretty close to what I think Agatha Christie wanted in Jane Marple. Hickson was 80 when she did this Marple series for the BB, this particular episode. The villains think her advanced age makes dotty. But she fools them.
