Further Beyond. The Beyond, #2

Twelve years ago, Phineas O'Hanlon - a mariner who ran and protected opium for a local triad "Three Finger Tang" during the aftermath of The Second Opium War - survived an attack from the living dead. He's spent the last few years of his life attempting to discover the cause of the reanimation. While reading over a newly acquired journal from ancient Rome, O'Hanlon and his caretaker are visited by two law enforcement agents who have questions about them.
As everyone's past is revealed, and secrets uncovered, can O'Hanlon discover the reason behind the resurrection of the deceased and move on with his life?
