When P.I. Sam Garrett is hired by eccentric billionaire toy maker and child genius Mozart "Mo" Chance—after his apparent suicide in the hills of San Francisco—Sam takes the case out of sheer curiosity. In a world where the Veil lifted a decade ago and exposed mythical beings living among humans, Sam faces a big challenge as the mystery surrounding the case deepens. The inheritors of Mo’s fortune—the uncle, the butler, the nanny and the bodyguard—all possess secrets, and some are willing to protect them at any cost. The trouble is that Sam’s partner and lover, Rex Ford, is suddenly under suspicion as well. Clouded by doubt, Sam continues to search for answers as tapestries of crimes begin to unravel and powers beyond his imagination are unleashed. If Mo endured horrific nightmares about monsters under his bed, there’s no telling what dangers await a nosy P.I. What dangers lurk in this darkness? Sam is about to find out.
