I was nervous about halfway through that despite my love for Asimov's writing I'd be disappointed by this book, since the solution to the mystery seemed so obvious, but as usual I was surprised by the ending. I especially enjoyed the references to the Foundation series — I already knew Daneel figured into the larger picture, but it was fun to gain a greater understanding of Baley's place in the chronology. I do disagree with some of (most of) the book's moral insinuations, but I was willing to excuse it in light of it being on the older side.
