Wolves
Neil Gaiman, I think, proposed the theory that in each of Wolfe's stories there is a wolf. I've been thinking about how this works out. In some cases, of course, the wolves are quite open, while in others they are hidden.
Cerberus has an open Wolf (the name of the Shadow Child when just one is left) and, by general agreement, a hidden Wolfe.
New Sun has the story of the boy called Frog, brought up by wolves.
Soldier has a known werewolf, and possibly hidden ones as well.
The Sorcerer's House also has a known werewolf.
_The Wizard Knight _ has nothing explicit so far as I can see. Could Able's miraculous dog really be a wolf?
In Long Sun I think I may have found one. Captain Serval (Hyacinth's ex-lover/estranged husband, depending who you believe) is named, I think, only once in the main text - we know his name mostly from the glossaries - and is generally called just 'the captain'. Now, the serval is actually a feline animal, but its name derives from 'lobo cerval', meaning 'deer-like wolf'. Strikingly, he has a round chin and a moustache.
I have not found any in Short Sun, but I will keep on looking.
Has anyone found any others?
