Joseph Spector is back, involved in a mystery that includes multiple locked room deaths, a murder and inheritance scandal from years before, a trio of soldiers injured in the Great War and a medium and her sketchy séances. This had all the makings of great mystery, and was arguably the most complex plot of the series to date. I did catch on to some of the tricks almost immediately and pretty much figured out who the killer likely was early on, though that in no way distracted from a pretty riveting story. The only real problem with it is the plot was so complex that it took an awful lot of exposition to fully explain everything. As complicated and original as the motives all were, I think a bit less layering, thus resulting in less required exposition, would have benefited the book more.
