The mysterious "Iron Face Man" was imprisoned on St. Margaret Island, 15 minutes from Cannes. There are about half an hour ferry trips to the island in peak season, but I went in the off season at the beginning of March, only two hours a ferry. It's about 12 o'clock and 14 o'clock each. The island is even more desolate in the off-season. The original castle on the island is like an abandoned dead city, with weeds everywhere, and wooden window panes clattering under the strong wind. Had it not been for the dozens of tourists who had boarded the same boat, I would have thought that I had gone to the wrong island or that the prison on the island had been closed because no one had visited it. The Iron Man was confined in one of the small chambers of the Island Museum and then transferred to the Bastille until he died.
