Posthumously published, this book is an excellent start to a potential series which alas will never be.
Conceived as a 'mysterious stranger/wandering man' affair, the book deals with the victim of hereditary lycanthropy living in small town America. Happy to have fallen through societiy's gaps, Marlowe Higgins takes life day by day, blending in and being as normal as possible, whilst dealing with the rage that burns inside of him. Every full moon, he sends his larger, hairier self out to feed - but only on those who deserve it (a la Dexter in many ways). When a serial killer comes to town and things start to become a little more personal, Higgins takes it on himself to track down the murderer before those close to him get hurt.
The story itself isn't overly special - take out the fact he is a werewolf, and you could have any type as the lead. What is speciual is the prose. Excellently written and obviously influenced by Chandler et al, (hell his name's Marlowe!), we have a strongly observed monologue dealing with the topic of disaffection in today's world. Higgins doesn't fit for more than the obvious reasons, but what we find is a gentle man who has lost everything he ever wanted and - a few bar fights aside - retains a strong sense of moral decency.
The only down side is it's pretty obvious who the murderer is - there is a very limited cast, possibly down to this being the author's first book and his need to limit the amount of people he deals with - but that aside I highly recommend this book, not just to fans of supernatural fiction, but anyone.
