The game is afoot!
Once again an alien race has tampered with Earth history, challenging Martin Chamberlain to another temporal contest. This time the stakes are higher, the strategy more daring.
Martin and Andrea travel to Victorian London in search of the true identity of Jack the Ripper. Then Andrea goes missing, and foes who shouldn’t exist in this time period begin appearing.
But all is not lost. Martin meets a surprising ally to help him defeat the aliens at their own game.
