Book 1

The Seventh Sinner

by Elizabeth Peters

Published 1 April 1972

At first, Jean Suttman thought she had died and gone to Heaven when she was granted the opportunity to study in Rome. But the body that's lying in the ancient subterranean Temple of Mithra--the murdered corpse of a repulsive and disliked fellow student--isn't her idea of heavenly. 

Now she is truly frightened, not just because small "accidents" seem to be occurring around her with disturbing regularity. It's the ever-increasing certainty that someone, for some unknown reason, is ruthlessly determined to do her harm. 

Jean's innocent underground excursion into a sacred pagan place has trapped her in something dark and terrifying, and even the knowledge that practical, perceptive fellow American Jacqueline Kirby is on the case won't ease her fears. Because there's only so far Jean Suttman can run . . . and no escape for her except death.


Book 2

When attractive American Jacqueline Kirby is invited to an English country mansion for a weekend costume affair, she experts only one mystery. Since the hosts and guests are all fanatic devotees of King Richard III, they hope to clear his name of the 500-year old accusation that he killed the little princess in the Tower of London.

Jacqueline is amused at the group's eccentricities until history begins to repeat itself. A dangerous practical joker recreates famous fifteenth-century murder methods - beheading, poisoning, smothering, and even drowning in a butt of malmsey. As the jokes become more and more macabre, one at last proves fatal.

Jacqueline puts all her observations together for a dazzling solution that will surprise even the most attentive reader.
