Something foul is afoot when the body of the Bishop of London is found murdered in the catacombs underneath St. Margaret's, a small country church. Sebastian St. Cyr, Viscount Devlin, has been called in by the Archbishop of Canterbury to investigate the murder and soon discovers there is not one, but two unexplained murder victims -- the Bishop and the mummified remains of another in the decaying crypts. Clues soon lead St. Cyr to uncover deep, dark secrets of some of the most prominent families in London society, including his own father. Seems the Bishop wasn't all that popular, after all. As St. Cyr begins to trace the Bishop's last day, he is dismayed to find that the last person to have contact with him was Miss Hero Jarvis, the very lady who had been avoiding Sebastian's attentions since their last encounter ended up in a compromising situation. Why had Hero been consulting with the Bishop? And how did Benjamin Franklin's son, William, figure into the life of the dead Bishop? Twist and turns and thrilling adventure await the reader in C.S. Harris' WHAT REMAINS OF HEAVEN. The 5th book in Harris' "St. Cyr Mystery" series, this is a mesmerizing tale of intrigue in Regency England. Part suspense, part romance, and part mystery, the story will keep the reader captivated to the cliffhanger ending. I was fascinated by the descriptions of Sebastian's friend, Dr. Paul Gibson and the early autopsy techniques he used as he and St. Cyr work to determine the death of the mummified victim. I also enjoyed the assertiveness and independence of the heroine, Hero Jarvis as she faced difficulty decisions for a lady of her time. Harris handles this delicate situation admirably. Fans of the Regency era of England will enjoy WHAT REMAINS OF HEAVEN, as will admirers of thrilling mysteries.
