This new and updated second edition of Souls Speak details the astonishing paranormal, true crime investigation into the fate of three boys believed lost in the vast caves beneath historic Hannibal, Missouri-Mark Twain's boyhood home. Their disappearances launched the largest cave search in US history, lasting a month and involving hundreds of America's best cavers, but no evidence of the boys was ever found. Later, the multi-year investigation involved three psychics who independently identified the boys as, perhaps, the earliest victims of serial killer John Wayne Gacy, many years before the madman's Chicago murder spree claimed thirty-three young men and boys. This vexing and astonishing mystery reaches its dramatic climax with the recently discovered Gacy deathbed confession, heard by a friend a few hours before the serial killer's execution. This brings Gacy's known kills to thirty-six. It is believed the depraved psychopath killed forty-five boys and young men by his own admission. The Gacy story continues to unfold, but the half-century mystery about the fate of Hannibal's missing boys has been solved.
