Three classic BBC Radio 4 full-cast dramatisations. The Mysterious Affair at Styles - starring John Moffatt as Hercule Poirot. A destroyed will, a shattered coffee cup, an old envelope - such are the seemingly unrelated details surrounding the murder of Mrs Inglethorp, mistress of Styles Court. Hercule Poirot, the methodical little Belgian, begins his first - and perhaps most fascinating - investigation. Murder at the Vicarage - starring June Whitfield as Miss Marple. In the sleepy little English country village of St Mary Mead, all is not as it seems. Under a seemingly peaceful exterior lurks intrigue, guilt, deception - and murder. Faced with a surfeit of suspects, only the inscrutable Miss Marple can unravel the tangled web of clues. The Sittaford Mystery - starring John Moffatt and Stephen Tompkinson. A blizzard has hit England. In the tiny village of Sittaford, on the fringes of Dartmoor, a party of six is gathered in Sittaford House, home of Captain Trevelyan. As evening draws in, a seance is proposed, but it reveals more than they had anticipated as the board spells out - TREVELYAN - DEAD!
