I really enjoyed this one. It carried a sense of inevitability that magnified everything that was happening. Never once did I catch a hint that he could ever get out of this, and losing the fingers one by one is just so terrible. Genius!
I did see the double-cross coming, but I wasn't bothered by the fact that I saw it coming. It just added to the inevitability that I liked so much.
The ending was really good, and I didn't see it coming. I like how the goals of the protagonist shifts at the end from trying to save the fingers, to trying to save his friend any more torture than he has to go through.
The Gypsy-style curse is kind of a worn out trope, in general, but this story made it seem fresh and new with a new sort of curse and well written characters.
