Convicted Spy Harry Gold Was Philadelphia's Benedict Arnold

I'm reading Allen M. Hornblum's The Invisible Harry Gold: The Man Who Gave the Soviets the Atomic Bomb (Yale University Press).

The interesting book is about a man who gave the world's most devastating weapon to the world's most evil empire.

Hornblum wrote about Gold in a piece for The Philadelphia Daily News. You can read the piece via the below link:
