I enjoyed this, despite all the "incredible coincidences" as the lawyer put it. There were one or two oversights that annoyed me, (view spoiler)[ such as the fact that Cathcart mentions the location of the gun in his letter and a few pages later they're speculating about whether or not he knew where it was. Granted the letter had just been read and introduced into evidence, but I'd think that's the sort of thing a decent lawyer would make a note of (hide spoiler)]. I've always wondered how Lady Mary and Parker met, and while this doesn't really show much of the development of the relationship that is seen in later books, it is interesting to see the first steps.
