It is the follow-up to Gypsy in Amber and also has Romano Grey as the main character.

Exiled rebels want it to rob the Communists of their pleasure, while an ex-Nazi art plunderer wants it to settle a very old score.

But it happened, and murder, mayhem and all hell broke loose... and only Grey knows the crown's true centuries old secret.
