The Moving Finger, Agatha Christie
The Book When Jerry Burton is ordered by his doctor to take a rest after a surviving a plane crash, his sister Joanna rents them a little place in Lymstock. The seemingly tranquil bucolic place is turned on his head when a rash of anonymous letters, all saying slanderous things, are delivered to unsuspecting people. Jerry and Joanna soon receive one alleging they are not siblings, but rather lovers. Despite this, Joanna starts flirting with the local doctor, Griffiths. His gossipy and bossy sister Aimee is unmarried and out to meddle in everyone's lives. The local solicitor Mr. Symimngton has a temperamental wife, two young kids and a 20 year old step-daughter, Megan, nobody notices. The lady they rented the house from had taken care of her mother and her sisters, and now, firmly middle aged, is stuck in the Victorian era that ended some 40 years prior. And the loads of maid, drivers, and gardeners around the place fill up the tiny village with all the gossip the need. ...
