With the discovery of Aladine-50, a vaccine against Creon fever, the importation of Earth dogs is all the rage in Demeter. Then three executives of Demeter Dogs Inc. are killed in mysterious circumstances and Brogan uncovers a plot that heralds an invasion of Altor by the Omera, an army of nomadic alien killers.
If like me you're not a pet lover (especially dogs) you'll also find this tale resistible. Guest star David Burke gives an object lesson on how to act your part, even under alien make-up, to all concerned with the show. Apart from him, this is a shaggy dog story, solidly told if unengaging.
