The Veiled Leopard (audio story)

Publisher's summary
Monte Carlo, 1966:

Four time travellers. Two missions. One costumed ball. The Doctor has sent Peri and Erimem to prevent the fabulous Veiled Leopard diamond from being stolen. Which is odd, seeing as the Doctor has sent Ace and Hex to steal the diamond. How will the two teams cope with this contradictory task? Will Peri's asp slip? Why does Ace have to pretend to be a French maid? How will Erimem cope with Pharaoh Rammalamadingdong? And can Hex really "do posh"?

Part One
The Seventh Doctor has previously talked to the Fifth Doctor about a plan to stop the theft of the Veiled Leopard, a precious diamond which contains a code to rebuild a world which was lost. They talked about returning it to its owners. Peri and Erimem stop the jewel thief and return it to its safe, completely ignorant that it is, in fact, a piece of alien technology.

Part Two
Ace and Hex go to find the diamond to steal it. Luckily, this happened after Peri and Erimem stopped the jewel thief. This time, the Doctor has explained why it is so important. Unfortunately, they arrive too late and have to stop another thief who is trying to steal the diamond so that the owner can become even more rich. Ace finds a shortcut, and stops the thief, but before she can leave, she must explain herself to Peri, Erimem and a few other people.
