Pretty darn stupid, frankly. I suppose
Abigail shortens to
Abbey! And I've heard of but never met a
Shula ...
And my first thought was that I read one book once - I think there are several in the series - that featured a female detective who was (a) an alcoholic and (b) known as Tempe or Tempy or something, but her actual name was
Temperance. Don't think I finished the book.
