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.

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.

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.
