The Button Man and the Murder Tree

A short story about a hitman suffering from a recently-acquired Joker deformity, this is a well-written story with some strong imagery. But there's not much more to it than that, with the story retreading familiar ground about anti-Joker prejudice and lacking in resolution. Being set in the early '70s it's unlikely to have any relevance elsewhere in the series, either. Yes, it's well done, but it comes across as filler.
