Imagine a world where death has meaning, where God exists and faith is untested. Where people die with the purpose of their lives made clear to them in blissful understanding. Such a world exists, hidden on the far side of the universe where a battered blue police box has just faded into being...

But unknown to the populace, unknown even to the Creator, an alien evil has stalked this world for hundreds of years. When the Doctor, Fitz and Anji arrive, they soon find themselves embroiled in the alien's final, desperate plans for this planet — and in the hunt for a murderer who cannot possibly exist...

Unnatural deaths are being visited on the people. Campaigns of terror threaten to tear this world apart. It seems that the prophecy of the Vanishing Point where all life shall meet all death under the Creator's aegis is coming to pass. For when God exists, prophecy, however fantastic or deadly, is fact.
