SUSSEX, ENGLAND, 1929. Mydworth is a sleepy English market town just 50 miles from London. But even in this idyllic spot, crime is never far away... Luckily the young and adventurous Sir Harry Mortimer has returned to Mydworth from his diplomatic posting in Cairo, with his unconventional American wife, Kat. And between them they are a match for anything - even murder. A DISTANT VOICE It's Midsummer in Mydworth, and celebrated medium Bellamy Smythe is in town with his lucrative supernatural show, claiming he can contact the departed. Still deep in mourning from the loss of her father in the Great War, spinster Alice Wetherby is desperate to make contact with 'The Other Side' and Smythe is happy to oblige - even though Alice is quite broke. Suspecting that Alice is being played, Harry and Kat investigate. As the Midsummer festivities intensify, they find themselves in a game of high stakes deception and clever tricks, where nothing is what it seems, and everyone is a suspect...
