Tasked by the queen to close the `Septimus Wave' case once and for
all, Captain Blake is facing a daunting task, for many questions
remain unanswered. Where did the spaceship buried beneath London come
from? What became of Lady Rowana and Professor Evangely? Meanwhile,
Mortimer is trying to pull Olrik out of the catatonic state the
villain has been in since his encounter with the ship's occupant. Has
the threat to the nation truly been vanquished?
Captured and then abandoned by Olrik, Mortimer is now lost at sea with no provisions. Fortunately, he can always count on Blake. Once reunited, and with the help of some old friends, the two British gentlemen continue their dangerous mission to stop Von Stahl from resurrecting the Third Reich using the evil power of the 30 pieces of silver... a mission that will take them throughout Greece and into the very Kingdom of Hades!
