'Castle' recap: Bloody diamonds in 'A Murder Is Forever'

castle-recap-a-murder-is-forever-nathan-fillion-stana-katic-abc.jpg"Castle" went back to the fun kind of murder in the most recent episode, "A Murder Is Forever." Yes, it was sad that a successful therapist and best-selling author got killed. But most of the episode's plot revolved around Castle and Beckett coming to an agreement on their new living arrangements.

Also, there was an incredibly big diamond. What's more fun than that?

Linus the Lion does not approve

Beckett doesn't like Castle's lion. And, believe it or not, that's not a euphemism. He actually has a lion hanging on the wall of his bedroom. This lion is Linus, a regal killer whose photo Castle bought with the proceeds from his very first royalty check.

Castle loves Linus. But Beckett finds the creature kind of creepy. Can a lion break up the couple?

No, of course not. Although there's some friendly bickering throughout the episode, Castle eventually takes Linus off the wall and replaces him with some seashells from that time he and Beckett went to the Hamptons.

And all's right in 'shipper land!

Did the apes do it?

Things are less right in the world of murders, which is kind of the way it tends to go. This episode's victim is a woman who worked as a therapist to high-powered couples. She based her theories on work done with the gorillas of Rwanda, so not everyone buys the therapy.

But she has a best-selling non-fiction book on the matter, indicating that at least some people buy it.

All of that doesn't matter when the therapist is found dead in her car on the night of a speaking engagement. Someone also went to the trouble to trash the car -- and the victim's apartment -- in an attempt to find something.

What's going on here?

Blood diamonds

The really strange part about the murder and all the searches is that almost nothing is gone. Only one patient file has disappeared, that of a hotel mogul getting divorced from his wife.
Castle and Beckett confront the man, only to find out that the therapist traded the file for a no-questions, no-identity hotel room. While the room is empty, the safe is not. In it, the detectives find a diamond.

It's a really, really big diamond too. We've got a motive, people!

Obviously, it's not the fixer. It's never the fixer.

The first suspect is, naturally, not the right guy. That would be a shady "fixer" type -- the audience actually sees the man with a knife at the murder scene. But that was just about searching for the diamond. He's not a killer.

Why was he there then? That would be because the fixer is working for a high-powered, philanthropist couple that wanted their diamond back. For some strange reason, the couple's trusted therapist stole what was supposed to be a fake diamond.

It's not fake, not really. The diamond is, however, synthetic. A synthetic diamond like that is even more valuable, possibly priceless.

But that still doesn't explain why a successful professional would steal it.

When someone goes to Africa, that's always important

Here's the thing: When it comes to television, a trip to Africa is **always important. No one just goes for research or work or even a vacation. If a character goes to Africa, it's a plot point.

Add in anything to do with diamonds and there is only one TV conclusion. This story is about conflict diamonds.

It turns out that the murder victim's boyfriend is an anti-diamond cartel activist. The couple first got together back in Africa but split up after witnessing a diamond-related massacre. When the guy became an activist, he broke up with the victim for her own sake.

The relationship was rekindled when she found out about the giant, synthetic diamond. If synthetic diamonds like this were possible, the natural diamond industry would collapse. Conflict diamonds, in particular, would no longer have any power.

Did the diamond industry resort to murder to keep its money?

Diamonds are a girl's best motive

Nope.

The motive was simpler in this case. When the victim wouldn't return the stolen diamond, patent infringement issues meant that its owners could have lost everything. But it wasn't the man -- the one who fabricated the diamond -- it was his wife.

She didn't mean to go all the way to murder, but diamonds make people do crazy things. Killing isn't a big stretch when gemstones enter the picture.
