When I realized I never fulfilled my promise. So here goes.
It was a mystery about the murder of a princess whose name might have been Juanita. The main suspect was the maid who might have been Caroline, and there was also a cat, maybe Almond. Her name slips my mind, but it turns out the killer was the victim's older sister, for no reason I can remember. I was taking to long to write it and I chickened out by deciding it wasn't very good. Sorry.
