The On-Line Spaceman and Other Cases

America's favorite science sleuth is back!

Seymour Simon is not only the award-winning author of the best-selling solar system series, he is also the creator of a brilliant series of brainteasers starring Einstein Anderson, a twelve-year-old whiz kid who uses science to solve even the most mind-boggling of mysteries. Launching the reissue of this popular series is The On-Line Spaceman and Other Cases, with ten all-new puzzles for Einstein -- and readers -- to solve. From the case of the crying rocks to the far-out Frisbee to the extraterrestrial from cyberspace, budding detectives will match wits with Einstein. And may the best scientist win!
