Decimus Fate

When the members of a remote monastery are struck down by a mysterious illness, they enlist the aid of a former demon hunter and a man known as the Sage of Blackfell House. Setting out to find a cure, they soon find themselves caught in a web of danger from ruthless crime lords, vengeful assassins, and evil magic users who draw their power from the realm of demons. But why should a mission of mercy attract such grave and dangerous threats? Because the Sage of Blackfell House was once a feared and notorious sorcerer, and his name is Decimus Fate. 

When two young men go missing, Fate and the Tutor find themselves caught up in a fight for survival against dark witches, mystical assassins, and subterranean terrors in the flooded sewers of Guile. Their search for the truth brings them face-to-face with the notorious Butcher of Guile. But could it be that the greatest threat comes from much closer to home?
