River Song has had more than enough excitement for a while. Deciding the universe – and her husband – can look after themselves, she has immersed herself in early 20th century academia, absorbed in writing archaeological theses.

But when a mysterious tomb is found in a dry, distant land, excitement comes looking for River.

Can Professor Song stop any more members of the expedition from dying? What deadly secrets lie buried within the crypt? And will British Consul Bertie Potts prove to be a help, or a hindrance?
