This was a fine conclusion to the first season; the mystery may have been smaller than usual but it was still entertaining. The story of how Ned and Chuck's friendship will be affected by her knowledge of his part in the death was well handled; it was both interesting and rather touching. It was good to see Paul Reubens return as Oscar Vibenius as he proved to be an interesting character in 'Smell of Success' and continued to be entertaining despite the viewer knowing he wasn't a suspect this time. The scenes were Swoosie Kurtz' character, Lily Charles, is hallucinating were hilarious and her final revelation to Olive came as a real shock; no doubt how Olive deals with this knowledge will be important in the next series.
Overall, a very good episode. The only negative is that I really wished someone had just clubbed the obnoxious kid, but he did have a lot of great one-liners. Also, the final scenes involving the monkey and the van just have to be seen.
Oh, and by the way, a Bonobo is NOT a monkey like you see in the show. Until recently they were called 'Pygmy Chimpanzees' and are only a bit smaller than a regular chimp--and look almost nothing like the tiny helper monkey you see here.
