Your `fact` function is the one that is partial
fact Buffalo Bob = True
fact Pig Joe = True
fact Slug Steve = True
-- what if all those patterns fail?
You should add a line to handle "every other case", like
fact Buffalo Bob = True
fact Pig Joe = True
fact Slug Steve = True
fact _ _ = False
Does that help?
