Doctor Who: City of Death: A 4th Doctor Novelisation

An unabridged reading of the brand new novelisation of a classic Fourth Doctor TV story by Douglas Adams
The Doctor takes Romana for a holiday in Paris - a city which, like a fine wine, has a bouquet all its own. But the TARDIS arrives in 1979, a table-wine year, whose vintage is soured by cracks in the very fabric of time itself. Soon the Time Lords are embroiled in an audacious alien scheme which encompasses home-made time machines, the theft of the Mona Lisa, the resurrection of the much-feared Jagaroth race, and the beginning (and quite possibly the end) of all life on Earth.
Aided by British private detective Duggan, the Doctor and Romana must thwart the machinations of the suave, mysterious Count Scarlioni - all twelve of him - if the human race has any chance of survival.

Douglas Adams and James Goss
