What You Don't Know

From the author of "Killing Me Softly" comes a terrifying thriller that will make you think twice before you open the front door...

It's Saturday morning. April Fool's Day to be exact. Malcolm Gilbert is on his way to play golf. His wife, Blair, is headed to the hair salon.

That's the plan anyway.

Then the doorbell rings.

And their nightmare begins.

For the next forty-eight hours, the Gilberts are at the mercy of sadists who unleash a seemingly unending campaign of terror against them.

But the question isn't who would attack the Gilberts.

The question is why . . .

The next time your doorbell rings, will you answer it?
