One man must make a journey across a once colonised alien planet. Abandoned by man when it was discovered that the species there were actually sentient, the planet is now a place of mystery. A mystery that obsesses the lone traveller Gundersen and takes him on a long trek to attempt to share the religious rebirthing of the aliens. A journey that offers redemption from guilt and sin. This is one of Robert Silverberg's most intense novels and draws heavily on Conrad's HEART OF DARKNESS. It puts the reader at the heart of the experience and forces them to ask what they would do in the circumstances. First published in 1970.

"SFWA Grand Master Silverberg (Voyagers) demonstrates why he merits that plaudit in this superior collection of three novels and one short story linked by the theme of humanity encountering intelligent alien life, or, as he puts it in his introduction, “reach out to meet others with uncertain hands.” “Those Who Watch” begins with an explosion over New Mexico that turns out to be a crashing spaceship; the ship’s three crew members survive and successfully pose as humans until three Earthlings see through their disguise. “The Man in the Maze” offers a less traditional story line, inspired by Sophocles’s tragedy Philoctetes and centered on diplomat Richard Muller. Muller’s the first human to contact the inhabitants of Beta Hydri IV—and he becomes a pariah upon his return to Earth. Silverberg shifts gears dramatically in “Tom O’Bedlam,” in which all of Earth’s governments have collapsed, and the eponymous lead has visions of fantastic crystalline beings that others dismiss as psychotic episodes. The anthology is enhanced by Silverberg’s introductions to each piece, which provide the personal and editorial background to the stories. Lovers of first contact fiction owe it to themselves to pick this up."--Publishers Weekly
