Lily Rowan is the sort-of girlfriend of Archie Goodwin, of Nero Wolfe fame. (See novels by Rex Stout.)

She is a wealthy, stylish 1930's chick who likes bullfighting and going out dancing. Lily is the only one of Archie's many female friends who is really a match for him.

Gorgonzola reminds me that her nickname for Archie is Escamillo--this is because the first time they met (in the novel Some Buried Caesar) he was escaping from a bull.
