An unabridged reading of a classic novelisation of the 1987 TV adventure featuring the Seventh Doctor and Ace. The TARDIS brings the Doctor and Ace to 1943, and a British Naval camp in North Yorkshire. Dr Judson is using the ULTIMA code-breaking machine to decipher the runic inscriptions at the nearby church; meanwhile Commander Millington is obsessed with his research into toxic bombs to hasten the end of World War Two. Nearby, an ancient evil stirs beneath the waters at Maidens Point. What connects all of these to a thousand year old curse?
