Penny Wintercraft-Hawkes's brother has returned from Hong Kong with a comfortable fortune and a new bride and is planning to build a house on land he's inherited. Because they want a house as much like an Elizabethan mansion as its "mod cons" will allow, they ask Penny's lover, Ringan Laine, to work on it as a consultant. Ringan is not only a noted musician but also a designer and architect well versed in the first Elizabeth's colorful period. The house is to be on the Isle of Dogs, and Penny's brother, his new wife, and Penny herself are delighted with the site. Ringan, however, comes away feeling very uncomfortable. A few weeks later, in London on business, he goes back alone, hoping to clear up any misgivings he has about the place. But this visit is even worse than the first. He hears women's voices, frightening and full of passion, coming from the air around him.
