Boy, when Leigh Brackett wrote horror, she wrote horror. This story, set in 1950s suburbia, is just chilling. Uncle Fred, the astronaut, brought a “neat little furry thing” back from Mars for his nieces and nephews. The “neat little furry thing” which might very well be the last of its kind has a profound impact on everyone it encounters.
Brackett pulls off an odd empathy for the creature, and at the same time, a low-level terror over what the creature is doing to the family and the neighborhood. Highly recommended. (Read in broad daylight.)
