In this third series of ten cases, Encyclopedia Brown's science-oriented rival continues to outsmart friends and enemies, wising off with corny quips even as his well-stocked brain is psyching out the stumblers and the humbugs. Sixth-grader Einstein finds the flaws in his high school friend Stanley's energy-saving schemes, and shows up a fraudulent Professor Kirkus before the so-called professor can rip off investors in his hurricane-stopping machine. Solutions always hinge on scientific facts or principles, which Einstein is always willing to explain to his less precocious friends. Readers who don't keep up with him will thus be informed on why giraffes can't scream, people can outrun snakes, planets don't twinkle, ice cut with a thin wire on weights will refreeze behind the wire, and a person-sized ant is impossible. But ""there is one kind of giant ant. An elephant."" Brash, but bright.
