In the city of Lormouth, Alphonse Hersham works for an organisation that hunts "dangerous supernatural entities". He is one of their most effective agents, but there is a big question mark over his head for the other people that work for the institution. How can someone so new and unknown be so good at their job?  His mysterious origins draw quite a lot of attention, and not all of it good. But when he learns of a family disaster, he is launched into something far greater than he could have ever imagined.
