There is a program coming up tomorrow, February 13th, on the Documentary Channel that fans of Agatha Christie may be interested in. Here's the info:
The Agatha Christie Code
The Agatha Christie Code introduces viewers to new fields of scientific enquiry using sophisticated computer analysis of Christie's every written word, her sentence structure, story arcs, red herrings, clues and so on. Produced with the cooperation of the company that owns the Agatha Christie estate, this documentary, just like one of her own famous stories, combines all the thrills of a real detective investigation.
It is on at 7 pm, and again at 11 pm (eastern time).
Sounds fascinating to me.
