Query: 19th Century England

This is only one story in Perry's list of over a dozen mysteries which recreate the atmosphere of late 19th century British Victorian hypocrisy and corruption. Her principle characters are Inspector Thomas Pitt and his well born wife Charlotte. While Thomas does his best to keep Charlotte out of his cases, when her curiosity is peaked her sense of adventure launches her into the fray. More than once it is Charlotte who uncovers the villain, even though she must probe for answers while exhibiting behavior appropriate for a woman of her class. In this story, Charlotte rattles the closets of the rich to unearth truths about the murder of two babies found in London's aristocratic Callander Square.
