Reception
Kirkus Reviews found the mystery "slight" and said of the purportedly previously undiscovered adventure "that [it] might just as well have stayed hidden." Publishers Weekly said that "Meyer cleverly plays with his audience’s expectations" and posited that Sherlockians would want a shorter wait for Meyer's next adventure. Joseph Goodrich of Mystery Scene positively reviewed the novel calling it a "a masterful concoction" and "an effective thriller, rich in atmosphere and period detail" The Washington Post reviewer Michael Dirda felt that the book has some "fine Sherlockian flourishes" but ultimately "the novel often feels talky and perhaps unavoidably somber and portentous."
