Travelling back in time to 1505 Florence in search of Leonardo da Vinci, the Doctor is surprised to instead find Count Scarlioni under a different name. Back in 1979, Romana and Duggan attempt to stop the Count's heist but arrive too late.
Pursuing the mystery of the multiple, authentic Mona Lisa's back to Leonardo de 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.—statmanjeff
