That stinks a kind deed turned into an offensive demand. Because of that, doubt there will even be a thank you. It was still a very nice thing to do.
I decided not to even communicate with them. I did get a threatening response from a Shieldmaiden looking, huge woman and, realizing that there must be more than Daddy's Old Book family value here, I turned the entire mess over to a law firm I've worked with in the past.
Now, I don't have to be involved while this gets sorted between those who give a shit.

If she hadn't threatened me, sent an officer of the court, avoided talking to me personally, I would have given it to them. They sent the Law, so now the Law has it.
That sounds wise.
Seemed like the best way to get my inbox a rest. Nothing from them when I had a soft heart about it. NOW, I can see why we are just now auctioning off the old bastards last things. I do not want to be a part of some goofy family struggle for dominance.
My Law Dawg tells me that I have all it takes to prove ownership of the manuscript to any court. I have decided to keep it.
FUCK THEM!!! They want to try to act shit and force something out of me, I won't play.
I was actually feeling very christian-like when this started. I mean I just wanted the classic record collection and bid on tools, just because someone else was and it was going for WAY TOO LOW. I didn't really care about the old tool cabinets. One of those old cabinets turned out to be a Browning gunsafe, BTW. It was the only thing in the lot that I could see when I bid. It stood wide open, hinting that all the other boxes were empty. Not the case. The other three were full of tools. Nothing great, just old tools which I collect.
Didn't even realize I was bidding on a Browning product.
Anyway, the other bidder gave up and another started for, presumably, the same reason I had bid on the boxes. NOT going to allow some random asshole to get TOO much of a bargain on something I have a passing fancy toward.
It truly was a great day.
