As we are approaching the Festive season I thought I would recommend some Christie reading material - and / or viewing.
The Adventure of the Christmas Pudding. This is a collection of short stories. The title story is set in an English country house where they adhere to the lovely traditions of Christmas, trees, midnight mass and loads and loads of food! Stars Hercule Poirot. Includes a foreword by Agatha describing her own remembered Christmases when she was a child.
Hercule Poirot's Christmas. A full length novel featuring the dapper Poirot - also takes place in an English country house at Christmas-time.
A Christmas Tragedy. Another collection of short stories from The Thirteen Problems. This one starring Miss Marple who is staying at a Hydro (a spa hotel) over Christmas.
The first two have been made into tv adaptations starring David Suchet but the last one has never been filmed.
