Folksy and idealistic young attorney finds himself morally obliged to take an unwinnable case, only to learn that a bit of amateur sleuthing might save the day. The central mystery isn't going to dazzle anyone, and its depiction of Lincoln as the best parts of Cicero, Sherlock Holmes, and MLK was a bit much, especially in a story that does such a good job of showing how morally compromised everyone around him is. But it's all in good fun, eager to please, and bolstered by some excellent supporting performances, so it's tough to be too hard on what amounts to a pretty entertaining episode with an admittedly clever premise. Think of it as a chapter of 'The Young Atticus Finch Chronicles.'
