Villa Cascana, Italian riviera. Benson has dreadful visions of ghostly mutant creatures crawling over the bed of his friend and fellow visitor Arthur Inglis. At breakfast the following morning Inglis hands him a pill box in which he has captured a caterpillar with curious crab like legs. Mindful of his ominous dream, Benson hurls it out of the window and into the fountain but the furry little fiend refuses to drown. It seems to have designs on Inglis. Only much later, when Inglis is no longer with us, does Benson learn the dreadful fate of the man who had previously stayed in the room.
