Deadbolt

Lock the doors and windows, check them exactly seven times, or else it might get in...

Every night when the clock strikes ten, there’s a knock at Mrs. Grayson’s cabin door and a voice that sounds just like her husband Greg, pleading for her to open it.

With her dementia getting worse, Mrs. Grayson can’t be sure what’s real or not anymore. But she is sure of one thing: Greg Grayson has been dead for years.

From the author of The Dark Thing comes a chilling new tale that will have you double-checking your locks before bed.
