Each time I read (or re-read) an installment of this series, I'm blown away by how carefully Harris researches the context of her novels. It's one of my favorite things about them -- getting a glimpse into London in the early 1810s. Not always (rarely, to be honest) are they pretty, but I like that the lives of ordinary people aren't swept under the rug in her stories, unlike most Regency-era fiction, where the focus is almost entirely on the idle rich and their amusements. Harris gives us a peek at the cost of those amusements, while at the same time delivering gripping mystery and compelling characters. You can't go wrong with a Sebastian St. Cyr book.
