Headscratchers: A Dirty Job

The man in the mint-green... golf attire?
On the back of the Wheeler Large-Print edition (and probably but not necessarily the other editions published in 2006), the cover synopsis describes Minty Fresh as "a strange man in mint-green golf wear at [Charlie's] wife's bedside". As far as I've been able to tell (and I read Coyote Blue a while back, so I didn't think that had anything to do with it), he's wearing a mint-green suit. Does anyone know where they [mis]conceived the idea that he was wearing golf attire?
