All irregularities will be handled by the forces controlling each dimension. Transuranic, heavy elements may not be used where there is life. Medium atomic weights are available: Gold, Lead, Copper, Jet, Diamond, Radium, Sapphire, Silver and Steel. Sapphire and Steel have been assigned. Christmas Eve. The Present. The Capital Palace, once a popular theatre, now stands unused next to a long-abandoned graveyard. Plans to celebrate the work of a dead playwright in the theatre draw Sapphire and Steel into a deadly maze from which there is little hope of escape. In a house where all the clocks stopped at midnight, Sapphire is at the mercy of an old woman with a familiar face. And Steel is reunited with an old ally... but for how long?
