Set in London in 1812, the Archbishop of Canterbury solicits Sebastian St. Cyr, Viscount Devlin, for assistance. Two brutal deaths have occurred in an ancient crypt and one of the deaths appears to be from the 18th century.
Sebastian begins delving into the situation and soon has a lengthy suspect list from the upper crust of London's society to the East End. He learns many secrets including those of his own family.
While she relates this story, Harris gives us insight into the social structure of the time, including clergy and lay people. The reader learns of the different personalities and how they deal with unearthed secrets and secrets they decide to keep.
'What Remains of Heaven' takes the reader to a time in history, Regency England, that is rarely explored in a mystery. Harris ties all the pieces of her plot together extremely well, building to a powerful ending. She takes us back in time and her presentation will appeal to readers.
