E-book exclusive extras:1) Christie biographer Charles Osborne's essay on Nemesis;2) "The Marples": the complete guide to all the cases of crime literature's foremost female detective.Even the unflappable Miss Marple is astounded as she reads the letter addressed to her on instructions from the recently deceased tycoon Mr Jason Rafiel, whom she had met on holiday in the West Indies (A Caribbean Mystery). Recognising in her a natural flair for justice and a genius for crime-solving, Mr Rafiel has bequeathed to Miss Marple a £20,000 legacy—and a legacy of an entirely different sort. For he has asked Miss Marple to investigate…his own murder. The only problem is, Mr Rafiel has failed to name a suspect or suspects. And, whoever they are, they will certainly be determined to thwart Miss Marple’s inquiries—no matter what it will take to stop her.Of note: Nemesis is the last Jane Marple mystery that Agatha Christie wrote—though not the last Marple published.
