My Name Is Legion: Roger Zelazny

As Albert Schweitzer, his first assignment was to find and destroy the power behind the attempts to sabotage a top secret nuclear project. The price of success was high - and Schweitzer had to kill himself in order to win through. On the second mission they called him Madison when he joined the team at the Institute of Delphinological Studies. A gang of dolphins were accused of murder and it was Madison's delicate job to clear them of all charges...Finally, he took the name of Donne on the deadliest mission of them all. A quasi-human telefactor called the Hangman had returned to earth to wreak vengeance on its four human  programmers. Donne had to eliminate the Hangman, whatever the cost, which was going to be difficult as telefactors never die...Cover art by Chris Moore
