Billed as a “thrilling new Sherlock Holmes mystery”, it was more a “tongue in cheek mystery” based on Sherlock Holmes characters.  The plot is complex, as you need in a mystery, the acting was fine, the conclusion tied up all the loose ends.  It just didn’t light my fire.  Thankfully it was one long act.  Sherlock Holmes mysteries are a genre—you know what to expect.  There were several clever character reversals, and I appreciated the twists.  I would call this standard matinee fare, and we attended the matinee.
