Nell and Will are a confirmed pair of amateur sleuths in this fourth entry in the popular Gilded Age series, and this makes the setting perhaps slightly cozier, but as usual, P B Ryan is spot on with her period detail. This is the best part about the series for me, as these books really do open a window into how both the high and low society of Boston operated. She thankfully doesn't shrink (Anne Perry style) from showing it, warts and all, and to reveal more would spoil the story. This is a fairly linear tale that could have done with at least one other plot strand to make it truly gripping, but with the historical detail, well-drawn characters and a faster pace than the other three books, it is probably the best entry yet.
