During Hammer’s time on death row at Terre Haute, he wrote two books on the Oklahoma City (OKC) bombing that killed 168: autobiography “The Final Escape, Secrets Worth Dying For” (2004) and “Deadly Secrets: Timothy McVeigh and the Oklahoma City Bombing” (2010) co-authored with Jeffery William Paul. The books are based on first-hand knowledge gleaned in conversations from Timothy McVeigh right up to McVeigh’s execution.
“Deadly Secrets” is an incredible, insightful and I believe credible read. For those who actually do read it, you will see that it’s detailed and accurate to such an extent that it seems unlikely to have been written by someone sitting in a maximum security prison without considerable insider input.
