The Fifth House of the Heart, Tripp Ben

Asmodeus Sax Saxon-Tang, a vainglorious and well-established antiques dealer, has made a fortune over many years by globetrotting for the finest lost objects in the world. Only Sax knows the true secret to his success: at certain points of his life, hes killed vampires for their priceless hoards of treasure.

But now Saxs past actions are quite literally coming back to haunt him, and the lives of those he holds most dear are in mortal danger. To counter this unnatural threat, and with the blessing of the Holy Roman Church, a cowardly but cunning Sax must travel across Europe in pursuit of incalculable evil--and immeasurable wealth--with a ragtag team of mercenaries and vampire killers to hunt a terrifying, ageless monster...one who is hunting Sax in turn.
