Historical thriller with plenty of twists and a bunch of interesting characters. The story generally moved along but at a slow pace.

An excellent entry in an excellent series. This book, like all in the series, is well-plotted, well-written, and moves along quickly through its chilling plot. Lily and Felix are asked to investigate what appears to be a very old skeleton buried in, yes, a rose bed in the garden of a house shared by a set of elderly siblings. That discovery leads to a much more disturbing series of events, and there are a couple of historical twists in the plot.
This book in particular has some very moving emotional moments and a disturbing villain, who has his own first person POV sections. I would highly recommend reading the other books in the series so the relationships among the main characters and the deepening ties between Lily and Felix make more sense. They are also just excellent books and well worth a read. Thanks to NetGalley and the publisher for an advanced copy. All views are entirely my own and offered voluntarily.
