(urth) The Avram Davidson Treasury

[Ab de Vos]

I just bought 'The Avram Davidson Treasury'. One story of this 
collection "Polly Charms, the Sleeping Woman" is introduced by Wolfe who 
writes "Davidson was never one to explain everything. No more am I" 
after which I believe he gives some clues to the story which I haven't 
read yet. The collection is touchingly introduced by Robert Silverberg 
and every story in it by a well known sf writer. I wonder if these 
forewords by Wolfe of which he wrote more than one shed any light on his 
writerly project.
