"Night of the Assassins" by Howard Blum … the plot (Operation Long Jump) by the Nazis to assassinate FDR, Churchill, Stalin at Tehran. My grandfather was in the US Army (Corp of Engineers) at Tehran at that time. German special forces were parachuted in. The Corp of Engineers had built water tunnels to supply the US Embassy. British traitor (code name Cicero) in the Turkish embassy was paid a million dollars to give out the location of the conference. Turned out, he was given counterfeit money by the Nazis. After the war, he tried to sue Germany for justice, but died broke. A double agent of the Soviet Union, arranged a reception party by Soviet troops, and the main German team (three dozen) are gunned down. But there are already six assassins on the ground before this. Ongoing breakdown of the plan, led to the previously unguarded water tunnels being guarded. And a $20,000 reward leads the Iranians to arrest the assassins.
