The title's a password and the author's real name, Jack Higgins, is another one; after his several successes, the eagle has landed sufficiently on his own feet to use his real name. The story also has a dual identity--who is the echt Martin Bormann, that ""man of the shadows"" who has cast the longest one in fiction of this kind. Here he has a lookalike made out of the skin and bones of a lesser Nazi, Strasser. Is it Bormann, or Strasser, who orders the final attack on the prominent prisoners in small Schloss Arlberg? Like General Canning flashing heroism from the Foreign Legion to Korea, and the lovely Claire de Beauville, ""winter roses"" with thorns. As they try to escape from Schloss Arlberg in a spray of gunfire, just who is back in the Bunker, lifting the body of Eva Braun? Higgins/Patterson does very well with this history reconstituted into action and it does equally well for him.
