LONELY EXPIATION by Siegfried Finser

Armand Dillon, the evil master mind of PTP Inc. reaches the pinnacle of his success and is still not satisfied. Manipulating his friends and enemies alike, he tries for the impossible: social acceptance in an upper class culture using the same tricks that won him success in business. Just when he thinks he is succeeding he's undone by strange qualities he doesn't know how to overcome. The innocent love of children, combined with adult strength, character, and balanced idealism, lead to his inevitable downfall. The surprise ending is a puzzle of human nature.
