 Why does The Scorpion go mostly unnoticed, despite reaching out to the newspaper?
Except that in the trunk lid the owner had burned in 'The Scorpion' in big black letters you could see half a block away." Stevenson followed Hastings' pointing finger, and saw again the crudely-lettered words, "The Scorpion" burned black into the paint of the trunk lid. It was in the crank letter's most obvious form; that is, the address had been clipped, a letter or a word at a time, from a newspaper and glued to the envelope. Dear Mr. Editor: The Scorpion has struck. The Scorpion fights crime. Crooks and robbers are not safe from the avenging Scorpion.
 Their first letter was disregarded, and their second was read by a different person.

Their first letter was disregarded, and their second was read by a different person.  The Scorpion hasn't made an appearance in person yet.  They wrote a crank letter, and so it was completely disregarded.
