Another of Perry’s excellent Victoria mysteries starring William and Charlotte Pitt, this one deals with the political ferment of the end of the 19th century: anarchists, protesters, politicians angling for advantage, and members of the Special Branch (where Pitt, formerly a London detective, now is employed), murderers, liars, manipulators. Pitt chases a murder suspect to France; at the same time, his superior is accused of embezzling and, in an effort to forestall his ruin, Charlotte Pitt goes to Dublin with the man. Perry is so accomplished at pacing, you’re most of the way through the book before the plot knits together. Satisfying, evocative, excellent characters. The entire series is well worth reading if you enjoy Victorian mysteries. It’s a 4.
