 |  THE 
              ALIEN HOUSE HAS MANY DOORS - AND THEY ALL LEAD STRAIGHT TO HELL!
 When Spencer Gill, Jack Turnbull and Angela Denholm were taken 
              by the Castle in Scotland, they found themselves playing Sith of 
              the Thone's monstrous multidimensional game to stay the execution 
              of Earth. They won - but in the process they made a deadly, devious 
              enemy of the alien master of The House of Doors. 
             Now Sith is back. And his game is more deadly yet. In worlds that 
              are known and in others beyond imagining, in mad machine worlds 
              and in some that can only be the products of a diseased mind - Sith's 
              new game will be played out to the bitter end. 
             For the game is rigged, the House itself as inscrutable as ever. 
              And its portals are all designed to lead Gill and his companions 
              ever deeper into worlds of uttermost terror. So, welcome, enter 
              - and die screaming! Your own worst nightmares await you in this 
              nerve-rending return visit to The House of Doors...  |
