The Horseman's Hunt

Reports of numerous people going missing only to be found lifeless and decapitated have reached New York.
You have been tasked to investigate these disappearances since Mr crane has been gone multiple months with no reply.
You will pick up where he left off and find any information you can about his whereabouts. Once you have collected enough evidence, you are to report directly back to New York. Good luck, and don't lose your head!
