⠀⠀⠀⠀⠀⠀I have an old puzzle I half-remember.
⠀⠀⠀⠀⠀⠀It was a great puzzle, and I remember the solution.
⠀⠀⠀⠀⠀⠀I could not for the life of me remember how the solution worked.
⠀⠀⠀⠀⠀⠀I must have been forgetting part of the question...
⠀⠀⠀⠀⠀⠀Well, here's my attempt at posting the riddle.
There were once three men at an old mostly wooden castle. The first only dreamt of silver and gold. The second only smoked English cigarettes, and the third had a sister with silver hair. One of them, unfortunately, was a habitual liar. When the neighboring castle burned down, the first said that he had seen a masked man light the house aflame with gasoline. The second had witnesses the fire start from the top of the castle to the bottom. The third, being the lead investigator, found a lamp in the basement of the ruined castle. Who is the liar, who committed the crime, and how did the crime occur?
⠀⠀⠀⠀⠀⠀EDIT: I noticed that this question was marked as a duplicate.
⠀⠀⠀⠀⠀⠀But, the duplicate linked has nothing to do with this! What's going on?
⠀⠀⠀⠀⠀⠀(for those intent on solving the puzzle, the whole question is valid information)
