Osama
While in London, I stumble across the real secret of Osama's disappearance. He has travelled back in time to 15th century Italy, and makes a living working as a muse for young renaissance artists. And because Osama has a wacky sense of humour, and a great big beard, he makes his speciality posing as the leading figures of early Christianity. Here, he makes an impressive Saint Jerome, as painted by Masaccio.
