"‘There’s Rosemary, that’s for remembrance." Published in 1945, Sparkling Cyanide is all about remembrance. It begins with six characters recalling the horrific death of Rosemary Barton, a beautiful but shallow young heiress poisoned by a cyanide-spiked glass of champagne while celebrating her birthday at a smart London restaurant. Rosemary haunts all six characters, each of them a suspect, throughout the story—and it’s not until her killer is found and her ghost laid to rest that the group can move on, though they will never forget. Adapted by Joy Wilkinson for BBC Radio 4, with a distinguished cast including Naomi Frederick, Peter Wight, and Amanda Drew, this wonderfully entertaining production retains the thrill of Agatha Christie’s clever, compulsive story. First broadcast on BBC Radio 4 - 30 January to 13 February 2012. 2 CDs. 1 hr 30 mins.
