The Cat who Walks Through Walls
4
Robert Anson Heinlein
Colonel Colin Campbell, alias Dr Richard Ames, 23rd-century writer, traveller and bon viveur, suddenly finds his life disintegrating around him. Framed for murder, married to the exquisite but enigmatic Gwen, fleeing for his life in the wild west enterprise zones of the moon, he is pursued by mysterious agents of an unknown power. If it wasn't for Pixel (a.k.a. Schroedinger's cat), a kitten with the disturbing propensity to walk through walls, the future of the universe might well have been different.
