" Published in 1943 and set on the coast of New Zealand's North Island, Colour Scheme highlights the impact that World War II had on the entire British Commonwealth. Colonel and Mrs. Claire run a shabby spa, Wai-ata-Tupu Springs, where they advertise the healing properties of the sulphur springs mud for a variety of medical complaints. One of their guests is Maurice Questing, who is suspected of being a Nazi spy, and who is attempting to take control of Wai-ata-Tupu Springs from the Claire family. Questing, it is generally believed, regularly signals to German submarines the location of Allied shipping that is leaving a nearby harbor so that the ships can be torpedoed. Unfortunately, Questing falls or is pushed to his death in a hot spring before his guilt can be properly established. It's up to Chief Inspector Roderick Alleyn, who has come from England to work with local authorities in New Zealand to unmask the killer and reveal the spy. "
