Undying World (Richard Blade, #8)

The Richard Blade novels were a series of adventures featuring the titular character (MI6A's special agent Richard Blade), who was teleported into a random alternate dimension at the beginning of each novel and forced to rely on his wits and strength. Richard Blade was distinctly British, and all the stories are set in England (at least at the beginning and end, with Blade being teleported to some other dimension for the bulk of each tale). A Train To Hell... It was foolish to take a train to Hell when he should be following the blonde to Paradise, but what could Blade do? The destination sign said: HELL. Blade stepped aboard and the doors wheezed shut after him. The train left the tunnel and shot into space. Collision. Wreck. No time to escape. Pain. Darkness. Nothing now. His last sob was one of relief. It was as it should be. Nothing was beautiful anymore. Blade awoke as usual, after going through the computer. In Dimension X. But it was different from any previous mission. No one was alive here; but they were not quite dead either. Not robots. Just sleepers. But they were able to kill. They wanted to kill. All they needed were the orders from Jantor or Sybelline. But who were Jantor and Sybelline? And how could they be stopped? It would be Hell....
