Alcatraz Screw is a firsthand account from a prison guard's perspective of some of the most storied years at the infamous U.S. Penitentiary at Alcatraz. George Gregory began his career as a guard for the Federal Bureau of Prisons in 1940. He takes the listener along on a correctional officer's tour of duty, showing what it was like to pull a lonely, tedious night of sentry duty in the Road Tower, or witness illicit transactions in the clothing room, or forcibly quell a riot in the cell blocks. Gregory provides an insider's account of the tenures of all four of Alcatraz's wardens and their sometimes contradictory approaches to administering the institution. He knew and regularly interacted with such legendary inmates as Robert Stroud (the Birdman of Alcatraz) and George "Machine Gun" Kelly.

Without glamorizing or demonizing either the staff or the convicts, Alcatraz Screw provides a candid portrayal of corruption, drug abuse, and sexual practices, as well as efforts at reform and unrecorded acts of kindness. Various incidents in the memoir convey the fear, hatred, frustration, boredom, and unavoidable tension of being incarcerated.

The book is published by University of Missouri Press. The audiobook is published by University Press Audiobooks.

"George Gregory arrived at Alcatraz during a critical juncture in the institution's history...In short, he saw it all - and he remembered it all." (John W. Roberts, from the Introduction)
