I must confess that even though I pride myself on being a true crime aficionado, I had never heard of the Cape Cod serial killer Tony Costa.

A shocking true crime narrative, Helltown reveals the secrets of this notorious serial killer Tony Costa, and explores the threads connecting Costa, and authors Kurt Vonnegut Jr and Norman Mailer in a seaside community that played host to horrors never seen before.

New in paperback, Helltown is $18.99
