i received this book through a book chain letter. Here is a description:
"In an unexpected twist, Agatha Christie's heroine, Miss Jane Marple, doesn't make an appearance in The Moving Finger until the second half of the tale. Instead, Christie has Jerry Burton, a man recovering from an airplane accident, narrate this intriguing mystery, proving once again her well-deserved reputation as a master mystery writer.

Burton and his sister are staying in a quiet English village where a number of residents - including themselves - are receiving a series of vile anonymous letters. But could these letters have triggered a suicide? When a murder soon follows, Burton steps in to help Inspector Nash find the culprit. Just as the case looks like it's solved, Miss Marple conveniently visits the quaint town and reopens the investigation, dazzling the villagers with her untangling of the murderous events."
