Bhagat Ram Talwar (1908—1983), a Hindu Pathan from the Northwest Province of British India, was the only quintuple spy of World War II.
Also known by the alias Silver, he was a freedom fighter and a peasant leader from the North-West Frontier Province in present-day Pakistan.
Bhagat Ram Talwar, also known as Rahmat Khan spied for Germany, Japan, USSR, Italy and British-ruled India for 5 years.
He took money both from Germans and Italians but when Adolf Hitler introduced Operation Barbarossa to invade the Soviet Union, Talwar or Khan worked for Russians to fool the Nazis.
Mihir Bose wrote a book on Bhagat titled "The Indian Spy: The True Story of the Most Remarkable Secret Agent of World War II" published by Aleph.
