Ordeal by Innocence

Accused of bludgeoning his mother to death with a poker, Jacko Argyle had maintained his innocence throughout his trial, claiming he was hitchhiking on the night of the murder and had been picked up by a middle-aged man in a dark car. The police were never able to locate this mystery man—until he shows up a year later. But Dr. Arthur Calgary arrives too late to substantiate Jacko’s alibi. For after serving just six months of his life sentence, Jacko dies behind bars following a bout of pneumonia.
Feeling a sense of duty to the Argyles, Calgary is surprised when his revelations reopen old wounds in the family, leaving him to wonder if one of them is the real murderer. . . . 

“Family tensions and suspicions are adroitly handled, and the solution is characteristically surprising.” — New York Times
“Agatha Christie is grade A fun.” — Phillip Margolin, New York Times bestselling author 

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.
