Lilian Jackson Braun (June 20, 1913 – June 4, 2011) was an American writer, well known for her light-hearted series of "The Cat Who..." mystery novels. The "Cat Who" books center on the life of former newspaper reporter, James Qwilleran, and his two Siamese cats, Koko and Yum Yum, in the fictitious small town of Pickax located in Moose County "400 miles north of everywhere." Although never formally stated in her books, the towns, counties and lifestyles described in the series are generally accepted to be modeled after Bad Axe, Michigan, where Braun resided with her husband until the mid-1980s.
