Spoiler warning! This is book 3 in an ongoing series. For those who prefer to go into a series completely unspoiled, this review will probably reveal details about the earlier books in the series. The story will also make a lot more sense if you start at the beginning, with A Study in Scarlet Women.
From Goodreads:
Under the cover of “Sherlock Holmes, consulting detective,” Charlotte Holmes puts her extraordinary powers of deduction to good use. Aided by the capable Mrs. Watson, Charlotte draws those in need to her and makes it her business to know what other people don’t.
Moriarty’s shadow looms large. First, Charlotte’s half brother disappears. Then, Lady Ingram, the estranged wife of Charlotte’s close friend Lord Ingram, turns up dead on his estate. And all signs point to Lord Ingram as the murderer.
With Scotland Yard closing in, Charlotte goes under disguise to seek out the truth. But uncovering the truth could mean getting too close to Lord Ingram—and a number of malevolent forces…
In the two previous books, Charlotte has appeared calm, logical, unflappable and unemotional. In this book, all evidence suggests that her best friend, Lord Ingram, has murdered his estranged wife and disposed of her in the ice house of his country estate and rather than investigating matters that merely provide an intellectual challenge, the stakes are deeply personal for Charlotte and the stakes have never been higher. While Charlotte is convinced that Lord Ingram is blameless, the evidence really is rather damning, and she and her associates will have to work ceaselessly to prove his innocence to the police and society at large.
