Miss Pink, an intrepid and unconventional murder investigator, is on her way to the remote estate of millionaire Jack Nielsen. She faces a hazardous journey alone, across the empty desert of Death Valley and through formidable mountain passes before reaching an animal sanctuary where pumas, bighorn sheep, eagles, rattlesnakes, and more are impartially protected. However, Miss Pink quickly finds that it's the people who could do with more protection... Soon she is investigating a couple of very puzzling murders - with all of Nielsen's family and staff as possible suspects. The search for the solution takes her through sandstorm and snowstorm, and up into the mountains twice in pursuit of killers. For an elderly lady who has come to the desert on account of her arthritis, she doesn't do too badly.
