Lord of the Silent / Elizabeth Peters 404 p.

Amelia Peabody Emerson returns in this 15th book in the series.  Amelia and her family return to Cairo, Egypt to research in the archaeological digs during World War I.  To keep her son Ramses out of the spy business that endangered her son in the past, Amelia sends him and his wife to check on old digs.   Tomb robbers are busy at work; dead bodies pile up; and, an old adversary is back.  Finally, the family and friends unite to solve the mysteries.Told with wit and a bit of romance, Peters interweaves British 20th century society, Egyptology, with murder mysteries delightfully.
