Summary George Brading, a Nemesis agent, goes missing for two days and when he re-surfaces, shoots an American officer in the Nemesis headquarters. Some time afterwards, he dies, presumably of poison. His widow tells the Champions that just before he disappeared, his brief-case went missing. Tremayne also tries to kill a doctor and he too has had his brief-case taken. Richard acts as decoy by having his wallet stolen. He is taken to a police station by a bogus officer where he learns, first hand, that both George and Tremayne were drugged with a mind-altering substance that turned them into assassins. Now he is programmed . . .to kill Craig. Craig must find the antidote to the drug before it is too late.
