Bones 9.19 was a classic anthropological mystery - in other words, it had all the elements that Bones does best.
It starts with evidence that would have stymied any other forensic team: ashes in an urn. How can people used to looking at bones make anything of these contents? Fortunately, the crematorium did a sloppy job, leaving all kinds of bone fragments in the mix. But I have feeling Bones and company would have cracked this case even if the urn of ashes had come from the best crematorium in the world.
And, indeed, the urn and its contents and wonders they point to turn out to be cornucopia of historically intriguing artifacts, ranging from a 4000-year-old chalice with a history of crime all its own, to a 1000-year-old narwhale tusk, to teeth of various people, and a much more recent artifact - diamond dust - which provides the crucial clue.
Along the way to sorting out these relics of the distant and recent past, and nabbing the killer, we get another shot at the very rich, which has become a theme of Bones - making it Bones meets Occupy Wall Street - ever since Hodgins lost all of his money. Who would buy nail polish with diamond dust? Just Beyonce, a name I didn't recognize (maybe it's fictional), and our killer.
But the funniest line in the episode comes from Cam, who, hearing about pizza ovens and crematoria, quietly quips, "And they ask me how I can stay so thin". Believe it or not, we had pizza last night, so I can sympathize. And, speaking of empathy, Cam had the most emotionally powerful scene in the episode with Finn, consoling him after Cam's daughter broke up with him. Those interns have had a tough time of it on Bones. I guess heartbreak makes a better story than happiness. Especially good to see, then that Bones and Booth - and Angela and Hodgins - are doing narratively just fine in their happy marriages.
