Frank Tuttle has written a series of books about a man, known as a Finder, that takes him on various cases and addventures. Includes trolls, a neighbor named Mama Hog, and of course there is also magic. Here is a description from Amazon for "Dead Man's Rain", the first in the series..
....Can a haunted man help the dead find peace? Markhat is a Finder, charged with the post-war task of tracking down sons and fathers gone suddenly missing when an outbreak of peace left the army abandoned where they stood. But now it's ten years on after the war, and about all he'll finding is trouble. This time, trouble comes in the form of a rich widow with a problem. Her dearly departed husband, Ebed Merlat, keeps ambling back from the grave for nocturnal visits. Markhat saw a lot of during the war, but he�s never seen anyone, rich or poor, rise from the grave and go tromping around the landscape. But for the right price, he's willing to look into it. As a storm gathers and night falls, Markhat finds darker things than even murder lurk amid the shadows of House Merlat. Warning, this title is rife with the walking dead, sarcastic butlers, barking dogs and ghostly dances....
