At first, Johnny Dixon doesn't believe Professor Childermass's story about Evaristus Sloane, the insane inventor of a fiendish, baseball-pitching robot. Then Johnny sees faces at his window at night, and senses he's being followed. Old Sloane has invented a new, improved robot, and he only needs one thing to bring it to life -- Johnny's eyes."A unique plot, marvelous characters, and non-stop suspense make for deliciously wicked fun". -- Booklist
