Voices in my head

So my first post on my first livejournal. I have the definite urge to write something deeply meaningful. Since I can't think of anything particularly deeply meaningful at the moment that isn't also trite, cliched, and schmaltzy, I will instead outline a fanfiction story that I really want to read but have no desire to write.

It's a CSI: Miami crossover with Highlander.
An old rich recluse dies under questionable circumstances that, among other things, leaves no body. Sufficient blood maybe for proof of death, but no body. The heir arrives: he is young, smooth, charming, and shows no mourning. Horatio Crane is deeply suspicious.
It's discovered that the accident was no accident, the death was intentional, and the heir did not arrive when he said he did. Horatio goes on one of his sanctimonious little rants about how he'll pin this on the heir.
Then it's discovered that the dead recluse was the only person capable of orchestrating the accident: it must have been a suicide, but what a strange suicide it is. There must be more to it. Horatio won't give up, he's still back-tracking the heir.
Then it's discovered that the heir is the recluse, starting a new identity because he looks too young to be older version any more.
There's no proof, it's not even clear if there's been a real crime. The CSI team has to let it go, but now knows that there are some very old people out there who don't look it. Interesting.

There are no challenges, no quickenings, no Game in this story, just a look at some of the other difficulties of being immortal.

Anyway, if anyone ends up writing this, or knows a story that's similar, please let me know so that I can go and read it.
