Jamie and Anna are Time Runners - they keep history moving in the right direction.

Their latest mission takes them to Britain in the 1950s, during the Cold War.

It's a time Anna knows well - it's when she's from before she fell through the cracks in time.

But something's terribly wrong. Why is a Russian spy attending a dinner party held by the man in charge of Britain's nuclear development?

Why is a ghostly image of Anna being dragged away by grotesque imp-like creatures?

Why does the mysterious Mr Prophecy never leave his room? And why is there a corridor reaching back through time hidden in the cellar?

If Jamie and Anna don't find out quickly, it could be too late.

It could be the end of the world...
