Murder of a suicide

Toby Dyke and the cherubic George just happened to be in the neighbourhood when Edgar Prees committed suicide by jumping from a cliff. And they were still on hand when the same Edgar Prees was found the following morning ...shot to death with his own revolver. Thus Toby and George, masters ofcriminal investigation, are thrust headlong into their oddest case - of a suicide that isn't. (from the cover)
