Jabez Wilson’s job suddenly ends with a note on the door of the offices where he works. When Wilson went to work one morning, the door of the office was locked. There was a piece of white cardboard in the window saying “ THE RED-HEADED LEAGUE IS DISSOLVED. October 9, 1890.”
There was no reason given. As we read the rest of the story, we find out why Wilson’s job ended. It ended because the job was just a ruse to get him out of his pawnshop. Criminals wanted Wilson out of the pawnshop because they were using its basement to tunnel into and rob a bank. When their preparations were complete, they no longer needed to pay Wilson to keep him out of the way.
