Weird Unseen RAYS Trap Master Crooks
How “Black Light” Brings New and Strange Magic to Aid Scientifically Trained Police in Solving Mysterious Crimes
By Edwin W. Teale
IN NEW YORK CITY, not long ago, perfume bootleggers hatched what they thought was a perfect plot, one that was absolutely undetectable.
Under direction of the gang, a small glass factory turned out imitations of the bottle used by a noted perfumer in selling one of his rare blends at $100 an ounce. Filling these with a cheap substitute, the crooks played their trump card.
Instead of counterfeiting the labels, they bribed the perfumer’s printer and obtained the original plate he had used. As a result, not even the most powerful microscope could find the slightest difference in the exteriors of real and bootleg bottles. The gang thought detection impossible. And it would have been but for a dramatic new weapon recently enlisted in the war against crime.
In his New York City laboratory, Dr. Herman Goodman, skin specialist and a pioneer in this thrilling new method of scientific crime detection, examined bottles brought by the frantic manufacturer.

By J. Edgar Hoover, as told to James Nevin Miller
SOME months ago thieves broke into an Ohio metal-working concern and stole a number of valuable copper ingots. The local sheriff’s office found a pair of gloves at the home of a suspect. A preliminary study indicated the gloves were impregnated with what appeared to be copper filings which might have been wiped from the surface of an ingot.
