The Elegant Variation does just that in Compare and Contrast. I liked The Sea a lot, so naturally I'm inclined to agree with Rafferty in this. But I have to say I try myself, when reviewing a book, not to compare it to an author's other works, because I think each work should be judged on its own terms. It's not a hard and fast tule, though, just a rule of thumb. Rafferty certainly is a close and perceptive reader, which makes his review especially pleasurable to read.
