The HUAC thing is a prime example of the stuff that makes up the H&L theory. It is just something taken out of context and presented as a "fact" to amaze the gullible reader. Zero evidence that this was the historic Marguerite.
Anyone who has read John Pic's testimony in its entirety will realize that he never said the LHO who returned from Russia was not his brother. He merely did not recognize a few of the photographs that were shown to him hwi9ch is not surprising since he did not see his brother for ten years. Another thing taken out of context and used to help bolster the H&L theory.
I'm a CTer but do not believe the Harvey and Lee (called by some, funnily, as Hardly Lee) baloney. I'd advise other readers to go to this very detailed and long thread on another forum. You'll find many of the silly, if not crazy, beliefs about this fictional caper including (non)photo alterations, sloping shoulders, and contrast(y) photos among other things.

The whole EF site has now become a vast echo chamber with little push back there and if there is any push back, you're either warned, are not read (they have a magical Ignore button there), or banned entirely.
