What happened to your skepticism ?
The beauty of the gas chambers is that no one really believes it. And, you don't need to read a book. There are exactly two 'homicidal gas chambers' in existence and shown to the public, the one already show at Majdanek, and one at Auschwitz. Unfortunately for the hoax establishment, it also has a large unbarred plate glass window. No book could convince a rational person, much less a rational skeptical person, that these rooms were 'homicidal gas chambers'. It is preposterous.
The 'gas chamber' at Auschwitz, the photo is from the interior and shows the door ....

We really have to believe a website that does not in the least bit provide info regarding the provenance of said photos and presents a book by the liar Fred Leuchter as an informative longer piece.
And why wouldn't you read a very well researched book on the topic by holocaust denier turned holocaust historian Pressac?
