Opening Statement:
     It was the design of Angelo Ricci and Joe Czanek and Manuel Silva to call on the Terrible Old Man.
What in Brown Jenkin's Name..?
     When a few thieves plot to rob a seemingly harmless old man, their plans go awry in a lethal manner. Yo ho ho.
Synopsis:
     A mysterious old man, rumored to be a retired rich sea captain, is often seen talking to his vibrating bottles. Two robbers enter the house to rob the man while a third waits outside. The man outside hears screaming and is confronted by the old man. Later, the three robbers’ bodies are found, slashed and trampled by many boots. 
From Dr. Armitage's Notes:

The Horrible Conclusion:
     But when he looked, he did not see what he had expected; for his colleagues were not there at all, but only the Terrible Old Man leaning quietly on his knotted cane and smiling hideously. Mr. Czanek had never before noticed the color of that man’s eyes; now he saw that they were yellow.
     
      Little things make considerable excitement in little towns, which is the reason that Kingsport people talked all that spring and summer about the three unidentifiable bodies, horribly slashed as with many cutlasses, and horribly mangled as by the tread of many cruel boot-heels, which the tide washed in.
