Cat in an Alien X-Ray" by Carole Nelson Douglas takes the Las Vegas gang on a science-fictional roller-coaster ride, as Midnight Louie, feline PI, and company encounter UFO enthusiasts, conspiracy nuts who are too bizarre even for tin foil hat therapy. An Area 51 attraction on the Strip threatens to bring more than starry-eyed enthusiasts to town. Once again it is up to that furballed PI Midnight Louie to keep his crew in line and save them from the attack of the creatures from the beyond or common criminals that prey on the innocent.
