The Moon Rock

"The Moon Rock" (1922) is Australian mystery writer Arthur J. Rees' locked-room conundrum. In fact, the room -- the murder scene -- not only is locked from the inside, but also two hundred feet up the cold wall of Flint House. And the house looms on the edge of a cliff in Cornwall. Slip, and a falling body would strike the pale Moon Rock and its legend of doomed love.
