The Ravelli Conspiracy, by Robert Khan and Tom Salinsky

Next in the sequence of First Doctor audios, this gives Peter Purves licence to do his famous and excellent William Hartnell impression, along with Maureen O’Brien as Vicki, in a pure historical story which takes place in Florence in 1514. Main characters are Giuliano de’ Medici, ruler of Florence; his brother Pope Leo X; and Niccolo Macchiavelli. There’s also a comic guard and a token Renaissance woman. It’s actually great fun, and my only complaint is that they all pronounce ‘Giuliano’ with a hard ‘g’ – it’s Julie-anno, folks, not Gully-anno. You can get it here.
