On July 23, 1991, Milwaukee chemist Lionel Dahmer discovered - along with the rest of the world - that his son Jeffrey was a murderer who, over a period of many years, had carried out some of the most ghastly crimes ever committed in the United States.

A Father's Story cannot claim to have discovered the ultimate solution to the enigma of either the criminal or his deeds. It is, in fact, not the story of Jeffrey Dahmer at all, but of a father who, by slow, incremental degrees, came to realize the saddest truth that any parent may ever know: that following some unknowable process, his child had somewhere crossed the line that divides the human from the monstrous.

This memoir is not a refutation of charges, an attempt to change the record. It is both a touching family memoir and a haunting confession - the searing account of a man who never relented in his effort to fathom the deepest quarters of his son's affliction, even as they pointed to his own.
