Geoffrey Household: Rogue Male

The behaviour of a rogue may fairly be described as individual, separation from its fellows appearing to increase both cunning and ferocity. These solitary beasts, exasperated by chronic pain or widowerhood, are occasionally found among all the larger carnivores and graminivores, and are generally males, though, in the case of hippopotami, the wanton viciousness of old cows is not to be disregarded.
