Finally a plot that's more captivating than the boring countryside feuds we got used to: art forgery. Barnaby turns to libraries to solve crimes and it's great to see it takes a bit of intellectual expertise to find the culprit, instead of the usual ivestigation. The main suspects are more or less dull, and the Hogson collector looks like Richard Branson. Jones was always kind of dull, and his character really needs a bit of direction, because he doesn't seem to be anything more than an assistant, with an occasional pun or side-story. All things considered, not really the top of the pile, but not a wasted time.
