The book is Ratline: Soviet Spies, Nazi Priests, and the Disappearance of Adolf Hitler by Peter Levenda.
Here is a site concerning it:
I know the consensus is he died via suicide and dead but I am only curious if there is a shred of doubt.
I think the russians took the burnt bodies that supposedly was hitler and his main squeeze.
Bodies were burnt... a man like hitler could have easily had a jew's teeth altered to be like his and killed in his place.
