German Medieval stained glass and the sinister myths that surround its making are at the core of this psychological thriller, where glass strewn bodies are regularly discovered and a parade of shady characters seems to pursue the daughter of a glamour-seeking professor. He single-mindedly drags his unwilling family to a remote Teutonic castle, whilst he searches for the fame and glory of discovering that which was thought to have been destroyed. His obliviousness to the dangers to which his family is exposed is breathtaking.
It is a long novel which could have been shorter for improved readability; at times the tension seems to stall. The central character, her sister and the German youth who befriends her are credible, but most of the adults seem a bit OTT. The demon himself proves a bit of a letdown at the finish.
