Description: Pursuing the mystery of the multiple, authentic Mona Lisa's back to Leonardo da Vinci's workshop in 1505 Florence, the Doctor meets Captain Tancredi - the very same man he's met as Count Scarlioni in 1979 Paris. Politely but firmly invited to tarry, via a set of thumbscrews, the Doctor can't help but answer a few of the gracious Captain's most urgent questions.
