Sanctuary is an original novel written by David A. McIntee and based on the long-running British science fiction television series Doctor Who.

The novel was unusual for being a purely historical story in which no science fiction elements appeared beyond the basic premise of the series.

As the Albigensian Crusade draws to its bloody conclusion, men inflict savage brutalities on each other in the name of religion.

Forced to temporarily abandon ship, the TARDIS crew find their lives intertwined with warring Templars, crusaders and heretics.

While the Doctor begins a murder investigation in a besieged fortress, Bernice finds herself drawn to an embittered mercenary who has made the heretics’ fight his own.
