Harris attended school in Weymouth, and then studied at the Central Saint Martins College of Art and Design, the Chelsea School of Art and the Courtauld Institute. She served in the British Red Cross Nursing Auxiliary Westminster Division during World War II, and has worked as a picture restorer, a reader for Metro-Goldwyn-Mayer, and a children's book reviewer for The Times from 1970 to 1973. She won the Carnegie Medal in 1968 for The Moon in the Cloud. This book was the first in a trilogy set in ancient Egypt. The subsequent books were The Shadow on the Sun and The Bright and Morning Star. The book was also the basis for a 1978 episode of the BBC series "Jackanory." Other books dealt with topics as diverse as terrorism, magic and futuristic totalitarianism.
The Shadow on the Sun is the darkest, and I think weakest, of the trilogy. It focuses on Meri-Mekhmet, who is courted by a mysterious young man but rejects him when he turns out to have a wife and multiple concubines. She is, in turn, courted by the Prince of Punt, who abducts her. Reuben and his cat Cefalu, back in Egypt with Reuben's wife Thamar, become involved.
On rereading I found the characterisation of the Prince of Punt and his people rather racist, and Reuben's victory trivial and hastily described. Still, some lovely scenes in the Chamberlain's water garden and the King's palace, and on the waterfront of Menofer.
So this one takes place after the flood.... When Reuben and Thamar start to feel they may have outstayed their welcome with the Noahs and decide to return to Egypt and find out how Merenkere is getting on. And just as well they did because love is not going well for the young Pharaoh when the object of his affections feels that his Great Royal Wife and collection of 93 foreign princesses may be an obstacle to their future happiness. As good and as witty as the first one and just as many cats.
