By J L Carr, read in eight parts by Samuel West.
Tom Birkin, a shell-shocked survivor of the First World War, travels to a remote north country village to uncover and restore a suspected medieval wall painting.
But why was it covered in the first place? Charles Moon, also a war survivor, is there in search of a lost grave.
As they work through the hot summer month uncovering the mysteries, the two men find some much-needed peace and tranquillity.
