The novel “The Slitheen Excursion” by Simon Guerrier was published for the first time in 2009.

June is visiting Greece as part of her classical studies at the university. She’s about to finish her journey and wants to see the Acropolis but during her excursion she sees what appears to be a British Police telephone booth with a man coming out and running towards the nearby caves. Curious, she follows him and sees him animatedly arguing with strange creatures that apparently want to destroy the Parthenon. She decides to intervene and helps him to capture the aliens.

June asks for explanations and discovers that the strange man is the Doctor, who doesn’t explain the events but, when he discovers the girl’s interest in ancient Greece, suggests that she travel with him back in time. The idea is to go to 480 B.C. but the discovery of an anomaly in 1500 B.C. leads to a change of plans, especially when the arrival at the new destination occurs with an explosion that leaves the Doctor stunned.
