At the end of 'Skulduggery' there is a short character introduction for "Skeleton" that came from "Batman: Gotham City Secret Files and Origins". It is just a small couple of pages to introduce the villain, but I found it really integrating and would like to read on.
Does anyone know what books continue from this character introduction so I can read the rest of this story for Skeleton that started with "Skulduggery"?
I know the original writer left Batman but did another writer pick up this story or did it just fade into nothingness?
