This volume of the collected works of one of the founding fathers of the “golden age” of American fiction includes two works. In the novel “The Cat Walks Through Walls,” the unpredictably developing plot is full of amazing events and adventures of heroes, for for whom life in space has become everyday life, and the history of its exploration has become destiny. Subtle intrigues, secret agents, desperate adventures, the inexhaustible power of humor and irony of the great master... “Sailing Beyond the Sunset” is the last novel by Robert Heinlein, in which he ties into a single knot the plot lines of his numerous science fiction works. The Universe created by the author is not a linear world, but a bundle of interconnected parallels of time, each of which takes its place in the “History of the Future” that Heinlein created throughout his life.
