It's March 24, 1953, at 10 Rillington Place in Notting Hill, London. Inside a run-down rowhouse,

43-year-old tenant Barristered Brown taps a nail into a wall with his hammer.

To his frustration, though, it slips straight through with almost no resistance.

He steps back and shakes his head.

All he wants is a small shelf for his radio here, and yet every nail he's tried refuses to

hold.

So Barrisford wraps his knuckles against the wall trying to find out the problem.

The whole thing sounds hollow, not at all what he expects. So he gives into curiosity, and reaching for

the edge of the wallpaper, he peers it from the wall. There's no drywall behind it, just a wooden

panel. And in the gaps around its frame, Barrisford can see that

there's a dark alcove. Curious, he finds a flashlight and shines it inside. The beam lands on a woman's

back. Beresford stumbles backward, his breath catching in his chest. When he regains his composer,

he looks closer. The woman is seated upright,

her back to him, her head slumped forward over her knees. And what looks like a thin

blanket is draped across her bare shoulders, but her skin is gray, and she is clearly dead.

For a moment, Beresford can barely move. His mind refuses to make sense of what his eyes are seeing.

Then he inches closer, casting the light farther back into the alcove. But the flashlight

slips from his fingers when he catches sight of what's next. There's not just one body, but two.

When police arrive on the scene, the horror only gets worse.

Hidden farther back in the same alcove is a third woman's body.

Then they uncover a fourth beneath some loose floorboards in the front room.

But even this isn't the end of the horrors connected to this house.
