Raymond King Cummings. His career resulted in some 750 novels and short stories, using also the pen names Ray King, Gabrielle Cummings, and Gabriel Wilson.
I went into this quick little story with no context of what I was getting myself into. And boy, was it fun! Really short, but really clever. A quick, one-sitting read with a tiny bit of mystery to it.
Boy considered nuts for his passion for chemistry. Outwits thieves with chemicals. Wins the hand of his girl. Could have been the story of a Bollywood/Hollywood movie if the passion for chemistry was replaced by passion for music/dance/cars. Not an original plot,and the presentation is dull.
