" This third installment was not as satisfying as the first two. Possibly it was because the story was closely involved with Sherlock's brother Mycroft. I prefer some of the other regulars and this book hints that the next one stays closer to HOLMES MANOR and that would probably include more action from Matty and Virginia. That said, there were a couple of hair-raising sections but the whole "Paradol Chamber" gang was a little far fetched and unfortunately the heart of the story. I liked the first murder scenario and the theater troupe plot twist but the author could have done more with it in my opinion including expanding upon Sherlock's use of disguise - not just seeing others use techniques. Also when his brother states that they will go in disguise to Moscow - and the "disguise" amounts to a name change?!? Totally missed the opportunity there! A 2.5 star rating. "
