1977. A small town is shaken by a series of murders committed by the mysterious "Lady Killer." Bet Greer—young, rich, eccentric—becomes the ideal suspect: she was seen running away from the scene of one of the crimes.
But the court acquits her, and ever since then, she has almost never left her mansion.
2017. All of Shay Collins’ free time is devoted to a website with the intriguing title "The Book of Unsolved Cases," where she gathers information about crimes for which no one was punished.
After accidentally meeting Bet Greer, Shay becomes determined to interview her—and, strangely enough, Bet agrees.
The temptation to learn the truth about one of the most unusual cases is too great, even though every time Shay crosses the threshold of the dark, unfriendly house where time seems to have frozen, chills run down her spine.
What if the smart and charming Bet is actually a cold-blooded manipulator-killer? What if other dangers lurk in the darkness that surrounds her terrible mansion?
