How would you interpret “squealing” here?
Mrs. Brown has been hiding mail. Filing it in the boxes for the attic without letting me see it all first, as is the custom. I caught her out and made her show what she’d been holding back. She insists nearly all the mail is the same as ever, it’s only a handful that are “not very nice.”
“We say onions to H. W. Shepherd!” is the general sentiment. Shepherd the squealing pathetic traitorous free speecher, the Communist.
How would you interpret “squealing” in the last sentence?
PS: the narrator, i.e. H. W. Shepherd, was a novelist and Mrs. Brown was his secretary. The mail refers to the letters from the readers.
Thanks. And this excerpt is taken from The Lacuna by Kingsolver.
