The hate disease

"The Hate Disease" by Murray Leinster is a science fiction novel written in the early 1960s. The story follows Calhoun, a medical officer aboard the Med Ship "Esclipus Twenty", as he embarks on a routine health inspection mission to Tallien Three. Upon arrival, he discovers that the planet is in the grip of a mysterious and terrifying epidemic that turns its inhabitants into violent, parasitic beings referred to as "paras." Alongside his fuzzy companion, Murgatroyd, Calhoun must navigate the chaotic landscape where societal order has collapsed and danger lurks in every corner. At the start of the novel, Calhoun and Murgatroyd approach their destination in overdrive, preparing for an inspection of an area that has been neglected for years. Their arrival is met with urgency when they receive conflicting communications about an emergency situation on the planet. As tensions escalate and a health crisis reveals itself, Calhoun learns that the paras are not only irrational but form an organized group that poses a direct threat to him and to the norms of society. The narrative sets the stage for a gripping exploration of insanity, fear, and the struggle for survival on a planet haunted by a dark transformation that could extend beyond its borders.
