Books in The Agatha Christie collection series

Agatha Christie's first ever Miss Marple mystery, reissued with a striking new cover designed to appeal to the latest generation of Agatha Christie fans and book lovers. 'Anyone who murdered Colonel Protheroe,' declared the parson, brandishing a carving knife above a joint of roast beef, 'would be doing the world at large a service!' It was a careless remark for a man of the cloth. And one which was to come back and haunt the clergyman just a few hours later. From seven potential murderers, Miss Marple must seek out the suspect who has both motive and opportunity.

While visiting Tommy’s Aunt Ada at Sunny Ridge nursing home, Tuppence encounters some odd residents including Mrs. Lancaster who mystifies her with talk about "your poor child" and "something behind the fireplace."When Aunt Ada dies a few weeks later she leaves Tommy and Tuppence a painting. Tuppence is sure she has seen the house in it before, a recognition that takes her on a dangerous adventure involving a missing tombstone, diamond smuggling, and a horrible discovery of what Mrs. Lancaster was talking about.
