This is yet another fabulous book by Laurie R. King.
She keep Russel and Holmes fresh and exciting.
The setting, pre-WWII, is portrayed as the slowly creeping presence of fascism. The historical reality of who finds that option desirable is fascinating.
Add to that the central question of where the missing woman went and why. As that unfolds, we get another chilling aspect of societal norms of the time.
Thank goodness for the creativity and tenacity of Russell and Holmes (and Laurie R. King's amazing research and imagination)!
