Supergirl--Action # 268

This is a pretty typical DC mystery story. Linda Lee accepts a week-long internship on the Daily Planet, when electrifying news breaks. There is a Supergirl on Earth, who came from the planet Krypton. At first Linda worries that perhaps her robot has performed the super-stunts. Then she fears that maybe she was affected by Red Kryptonite and is revealing herself during events that she later forgets. Eventually the new "Supergirl" shows up at the Daily Planet, but Linda is ready. She exposes the fake Supergirl to phony Green K, causing her to pretend to be affected. But when the Green K is exposed as bogus, so is the new Supergirl. She turns out to be an actress hired to hype a new movie.
