This is Rita Mae Brown, author of fifteen detective novels in which a cat, Mrs Murphy, solves murders. Her most recent, The Purr-fect Murder, is in stores now.
Her credited co-author is her cat Sneaky Pie Brown; their other titles include Puss 'n' Cahoots and Whisker of Evil. Oh, and she also used to date Martina Navratilova. She clearly doesn't need the cat desk tray shown below; not if Sneaky Pie's doing all the typing anyway.
