The Broken Scroll (The Glass Planet Book 6)

Anthopologist Antony Jacobs is once again thrust into controversy surrounding ancient artifacts. Only this time he gets lined up for murder. His autistic son is involved but he doesn't know quite how. Can the murder be solved? Or does the muderer get away completely? And who and why would want to kill a respected professor at the university in such a personal and twisted manner?
And why would they try to take the boy with them? History, Anthropology, ritual sex, ancient manuscripts.
