One minute, silly Heather Badcock had been gabbling on at her movie idol, the glamorous Marina Gregg. The next, Heather suffered a massive seizure. But for whom was the deadly poison really intended?

Marina's frozen expression suggested she had witnessed something horrific. But, while others searched for material evidence, Jane Marple conducted a very different investigation � into human nature.

Agatha Christie was born in Torquay in 1890 and became, quite simply, the best-selling novelist in history. Her first novel, The Mysterious Affair at Styles, written towards the end of the First World War, introduced us to Hercule Poirot, who was to become the most popular detective in crime fiction since Sherlock Holmes. She is known throughout the world as the Queen of Crime. Her books have sold over a billion copies in the English language and another billion in over 100 foreign languages. She is the author of 80 crime novels and short story collections, 19 plays, and six novels under the name of Mary Westmacott.
