I liked this a lot! Unfortunately the site doesn't quite cope with having the same word twice in different groups, even though it makes for an interesting twist. So in this case you have to select the right "greed" as the other one won't work. Really good otherwise, though, and pretty difficult.

Never heard of "In Dubious Battle" before. Could have been a better-known Steinbeck book (Cannery Row?) Otherwise ok

Repeat word means not a unique solution. Didn't think it even possible, don't think it desirable.
