As the couple entered the cell the three inmates rose from the lower bunk. Spotting the gun in Emma's hands, the mother shrank back and ushered the two girls behind her.

"I...I don't know what you want with us, but just take me. Let the kids go. Please. I can pay. I'll find a way. Please!"

Emma gave her a pitying smile. "It's not about money darling, you're here solely for our pleasure." Then, as if it needed clarification, she added, "all three of you."

"Pleasure?" The mother's eyes blinked in disbelief. "What the hell! You sick fucks! Let us go!"

She had some kind of East European accent that Bob had trouble placing. "You're not going anywhere sweetheart," he told her levelly.

Magda cast around desperately, and Bob could tell she was about to try something dumb. And she did, lunging at Emma and the gun. But before she could get her hands to it, Bob's right fist hit her square on the nose. She staggered back, hands to her face, blood trickling between her fingers.

"That wasn't too smart was it?" laughed Emma, and racked the shotgun. "They say this thing'll blow a hole in a dog big enough to throw a cow through"

"I think you mean..." interjected Bob.

Emma carried on regardless, "Maybe we should see what it does to Sugar Plum here. For science." She aimed the gun at little Maisie's middle.

"No!" cried the mother, "you couldn't. You wouldn't! She's just a baby!"

Emma cackled gleefully. "And we'd make you clean up the mess!"

"Someone will hear us and then the police will be here."

"Sorry sweetheart, no-one will hear you scream down here. And you should save your screams till later, when we can all enjoy them. So, you gonna be quiet now?"

The adrenaline was subsiding, the void filled by stinging waves of pain from her bloody nose. Her head dropped and she nodded resignedly.

The youngest was crying, a grizzled high pitched squeal, and the fifteen year old was sullen, silent tears streaming down her face from imploring eyes.

Abruptly, Emma's demeanour switched. She retrieved a box of sandwiches from the bag and flashed a warm smile. "Well, cheer up, we've brought you breakfast!"
