"The invention of displacement booths produced one hell of a crime wave. When a man in, say, Hawaii, could commit murder in Chicago and be back in the time it would take him to visit the men's room, he would have a seemingly perfect alibi. The police would have a problem. In his new collection of stories all about teleportation, deep space, black holes, artificial worlds and Louis Wu--our old friend from the 'known space' cycle--Larry Niven once again proves he's a master builder of fantastic worlds."--Pg.
