(urth) The Wizard - questions -- answers (spoiler)

[Russell Wodell]

What would be Sir Garvaon's motive for killing Gilling? (Rhyme 
unintentional) And why would Wolfe conceal this for so long?

For this and other reasons, I am fairly certain that Iddn is the murderer. 
She agreed to marry Gilling to achieve power, which she maintains with her 
army of giantesses, but killed him because sexual congress would mean her 
death either in coitus or in giving birth to a giant, as Wolfe makes 
gruesomely explicit.

If I'm right, this further underlines the increasing strain of misogyny in 
late Wolfe...
