I'm a sucker for a good Sherlock Holmes retelling and, for all that Addison does not necessarily feel beholden to recreating all aspects of Holmes and Watson's personalities (although you can see she's invested in going back to the actual source material rather than the overly mercurial and frankly obnoxious Holmeses of recent media fame...) and is definitely interested more in bringing in the shape of the stories rather than the exact people, I rather think that's part of what makes this book work.
