On Nov. 30 he was registered under an assumed name in the psychiatric section of St. Mary’s Hospital in Rochester, Minn., where, during December, he was given 11 electric shock treatments.

In January he called me from outside his room. He sounded in control, but his voice held a heartiness that didn’t belong there and his delusions had not changed or diminished. His room was bugged, and the phone was tapped. He suspected that one of the interns was a fed.

During a short release he twice attempted suicide with a gun from the vestibule rack. And on a flight to the Mayo Clinic, though heavily sedated, he tried to jump from the plane. When it stopped in Casper, Wyo., for repairs, he tried to walk into the moving propeller.

I visited him in June. He had been given a new series of shock treatments, but it was as before: the car bugged, his room bugged. I said it very gently: “Papa, why do you want to kill yourself?”

“What do you think happens to a man going on 62 when he realizes that he can never write the books and stories he promised himself? Or do any of the other things he promised himself in the good days?”

“But how can you say that? You have written a beautiful book about Paris, as beautiful as anyone can hope to write.”

“The best of that I wrote before. And now I can’t finish it.”

I told him to relax or even retire.

“Retire?” he said. “Unlike your baseball player and your prizefighter and your matador, how does a writer retire? No one accepts that his legs are shot or the whiplash gone from his reflexes. Everywhere he goes, he hears the same damn question: what are you working on?”
