 Viewing this as an opportunity to reach a completely different audience, Vachss agreed and wrote a draft.
 He continued with his themes concerning child sexual abuse and explored the topic of child sex tourism.
 The publisher required Vachss to follow certain rules, like making a clear distinction between fiction and reality and prohibiting the Batman character from killing, cursing, or having sex.
