I'm reading the whole series, and up to book 6 now. I'm really enjoying them--I'm from NY, so the descriptions of turn-of-the-century NYC are of particular interest to me. Also loving the slow burn between Sarah and Molloy, the interplay between them and their families (and each others'), and the politics of class, gender, and corruption--can't wait to see how things unfold in the future books.
These are not dense, tightly plotted mysteries--even *I* can tell who the bad guy is, most of the time. But I'm reading them for the characters and environment, not the mystery piece. From that standpoint, these are very enjoyable books.
