Swallowed up by the Soviet prison system, the fate of Raoul Wallenberg, saviour of tens of thousands of Hungarian Jews during the Nazi holocaust, remains a mystery.

Recently KGB files have been opened and many Communist crimes have been fully exposed. Yet there is still no evidence, apart from a handwritten note of doubtful authenticity, to support the Kremlin's claim that in 1947 Wallenberg, then thirty-five years old, died of a heart attack in prison. On the other hand there is abundant evidence - none of it conclusive, but much of it highly persuasive - that Wallenberg remained alive in captivity long after 1947, broken in body and spirit, somewhere in the vastness of the former Soviet Union.

Righteous Gentile is the first book to tell the full story of Raoul Wallenberg's shining wartime exploits and shameful post-war incarceration.
