Chicago, 1922
The mysterious disappearance of Douglas Theodore Kimball, doctor in ancient languages and the former professor of Chicago University, left the police stumped.
Was he murdered? Kidnapped? Suspicion fell upon his nephew Thomas, the sole heir, but no evidence tied him to the crime.
Desperate to find his uncle and clear his name, Thomas Kimball turns to the Silver Dagger Detective Agency. What begins as a search for a missing man will plunge the investigators into a nightmare of forbidden tomes, things that stalk the night, and an ancient evil that does not sleep… it waits.
