Olive Bright, Pigeoneer

Isn't it fun to imagine a book as a movie?

Or in this case, as a season on Masterpiece Theatre!  
In the idyllic setting of Pipley in Hertfordshire, not all is at it seems.
All the juicy characters are here, including Olive Bright, eager to help His Majesty's Forces defeat the Nazis with her highly trained racing pigeons. When the local busy body turns up dead, and so many of the local villagers trained in the use of native plants as poisons, Olive must figure out who among them has turned to murder by foxglove to silence the local busy body. With Agatha Christie as her inspiration, Olive is unstoppable.
