- —The Catmaster and Agatha
The Catmaster appears to be in charge of an army of oversized cats (perhaps they are Maine Coon) that lurk in the library hidden under . Wearing a cat ears-shaped hat, puffing a cigar and covered in what can only be cat scratch scars, he appears to be surprised that the cats take a liking to Agatha. His bandoleers may contain catnip for emergencies.
