When calling a suicide hotline (because who wouldn't?), Tony was connected to Vicki Johnson, who saved him from his living nightmare. Vicki said she befriended the dying-of-everything-under-the-sun Tony, nursed him back to health, and helped him write about what happened. His 1993 memoir A Rock And A Hard Place came out when he was just 14. It became a bestseller, the movie rights were picked up by HBO, and it was even featured on the always-trustworthy Oprah. America couldn't get enough of the boy with a thousand Sin City stories in his life.
The "new epilogue" was a list of horrific drug addictions Anthony suddenly remembered he had.
But cracks started to show when people wanted to meet Tony, as Vicki had never let anyone meet the sickly, sickly boy. A few people had talked to him on the phone, and noted that he had an effeminate voice that was strangely similar to Vicki's. We know what you're thinking: the twist is that Vicki and Tony were long-lost twins! But shockingly, no. When 20/20 had a voice analyst examine some recordings, he concluded that Vicki and Tony were the same person. Gasp!
"True story" = A boy named Anthony exists somewhere.
"Certain names" = The shyster who wrote this.
