Digger James and the Amulet of Set

Stephen explained about the amulets, but he had one surprise to add "Ulf said that the red amulet of Set was very cold and the white Horus one was very hot. But when I touched them I found the reverse, though I didn't tell him that."

"Right, let's find them and get out of here" said Digger, this outfit is driving me up the wall"

Suddenly the doors opened. "Ah, professor, we are ready to start" boomed the voice of Ulf von Braun. "Herr Himmler will be watching from the balcony and we have an armed guard at each door in case anything goes wrong"

"Of course Herr von Braun" stuttered Digger, suddenly aware that Stephen had moved away to avoid being recognised.

"And here are the two volunteers, each wearing one of the amulets. Shall we begin?"
