The Old Man's Request

Fifty years ago, a group of college friends dabbled in the occult and released a malign presence on the world. Now, on his deathbed, the last of the students enlists the aid of three newcomers to banish the thing they summoned.
Hampered by the old man's greedy son, the wizened director of the university library, and a private investigator with a troubled past, can Russian anthropologist Anna Rykov, Doctor Harry Lamb, and Father Sean O'Malley gather the knowledge and resources needed to defeat the entity?
The Old Man's Request is a pulp adventure set in the 1920s, and the first part of the Utgarda Trilogy.
