*** A Letter of Mary, Laurie R King, 1997
Still rocking along in the Mary Russel series and still loving it. I wondered how the change in Mary's circumstances would change the atmosphere of the series. The answer is that it did nothing to hurt it, but in fact probably improved it. Can't be any more specific that that without spoilers.
I was delighted to encounter a certain gentleman sleuth of the era in Chapter 17. It took me a while to snap to the clues, but I had to smile at the deft way it was worked in without distracting from the story. I'll say nothing else so as not to spoil the discovery for others.
No more specific details to mention, other than that any Holmes enthusiast should definitely read this series, starting at the beginning.
