Julio Sham was the captain of The SS Prospero, a ship that is connected to VFD. Not much is known about him, except that his identity was made into a VFD disguise, and that he was probably killed by Count Olaf in The Wide Window. His identity was taken by Count Olaf in The Wide Window, the Snicket brothers in The Unauthorized Autobiography, and at least partly by Duchess R. in that same book. He was also one of the people with the initials J.S.
