This was a fairly average Sherlock Holmes pastiche. The mystery was easily solved but the motive was not clear. Once that was established all that was left was to resolve the love story
. The book should and could have been 30 pages shorter.
I felt the writing was strong but a couple of swift mood changes seemed awkward, "that escalated quickly" moments. There was also a poorly placed scene of passion between Holmes' cousin and his wife that just came across as bizarre.
