The Horus killings - P. C. Doherty

After the death of her husband Pharoh Tuthmosis II, Hatusu has confounded her critics by winning a great battle against the Mitanni. Aided by her lover, Senenmut, she is determined that all sections of Egyptian society should accept her as the first Pharaoh-Queen of Egypt - an acceptance that needs the favour and support of the priests. When a spate of killings takes place in the Divine Temple of Horus, the naturally superstitious priests interpret this as a sign of the Gods' disapproval of Hatusu's rule of Egypt. The royal city turns once again to respected judge Amerotke to find the truth.
