This short story by Maxwell Grantly outlines the silly mayhem that followed, the day that Tabby followed Mrs. Phossy into her workplace: an old Victorian matchmaking factory. What began with a simple accident with the phosphorous chemical (a reactive chemical used to make the match heads) nearly ended with the destruction of the whole city. Thankfully, the story has a happy ending (as all good stories should) but you'll never believe the crazy antics that link the start of the story to its ultimate happy ending.
