Under Plum Lake is a kid's book that also wowed the adults that read it. Right from the opening lines the reader is pulled into a world suffused with a sense of loss and then dazzled by a pyrotechnic display of storytelling. 'I went down again last night. I go every night now. It's August again, the same time of year, and I know it can still all happen again.' Lionel Davidson (1922-2009) was much admired by his his fellow writers - Graham Greene, Rebecca West, Frederick Forsyth and Philip Pullman among them. Davidson won the Golden Dagger award for crime thrillers an unprecedented three times, as well as scripting several films. Yet the eerily evocative Under Plum Lake remains an enigma, the only childrens book he wrote under his own name. It's a genuine one-off.
