Marking exactly 100 years since Agatha Christie wrote THE MYSTERIOUS AFFAIR AT STYLES, this special edition brings together the first Poirot novel with her last, and includes new cover paintings by Tom Adams, special introductions, and a unique letter from Hercule Poirot himself never before published in the UK. CURTAIN, written 25 years later but not published until 1976, takes the elderly Belgian detective and his old friend Captain Hastings back to Styles, the rambling country house where they solved their first murder together - and where history seems determined to repeat itself. CURTAIN was the last Poirot novel until Sophie Hannah's hugely successful continuation novels, THE MONOGRAM MURDERS and CLOSED CASKET. This limited edition boxed set includes: * A unique pull-out letter written by Agatha Christie in 1936 in which Hercule Poirot introduces himself to his editor, never before published outside the USA * A newly discovered article by Agatha Christie, Drugs and Detective Stories, written for University College Hospital Magazine in 1941, in which she reminisces about the inspiration for her first book * Agatha Christie's original unpublished courtroom ending to The Mysterious Affair at Styles, introduced by Christie expert Dr John Curran * Brand new cover paintings and an introduction by Tom Adams, Christie's celebrated cover artist from the 1960s onwards
