Conway is replaced on the ambulanceship Rhabwar by Diagnostician Prilicla. Conway visits healer Khone on the planet Goglesk, and witnesses first-hand their destructive racial mass-hysteria response to physical proximity. He inadvertently links minds with Khone and learns a great deal more. Back at Hospital Station, Conway decides to treat some Hudlar accident victims with a rear-to-front limb transplant, because stranger transplants require permanentexile. Conway also proposes staving off geriatric Hudlar problems by elective amputation. At the end, he successfully delivers a sentient telepathicUnborn from its violent non-sentient Protector.
