The chilling account of a pivotal encounter between innocence and ultimate malice, Darkness Under the Sun is the perfect read for Halloween--or for any haunted night--and reveals a secret, fateful turning point in the career of Alton Turner Blackwood, the killer at the dark heart of What the Night Knows, the forthcoming novel by #1 New York Times bestselling author Dean Koontz.

There once was a killer who knew the night, its secrets and rhythms. How to hide within its shadows. When to hunt.
He roamed from town to town, city to city, choosing his prey for their beauty and innocence. His cruelties were infinite, his humanity long since forfeit. But still . . . he had not yet discovered how to make his special mark among monsters, how to come fully alive as Death.
This is the story of how he learned those things, and of what we might do to ensure that he does not visit us.
