obsessed with her, and that the two of you almost broke up over it.â
âThatâs a lie!â I yelled.
âSo youâre a lesbian?â said Luke, more surprised than angry, it seemed, by this sudden revelation.
âAre you saying you never slept with her? Is that what youâre saying, Karen?â
I hesitated. It was enough.
âYou killed Rachel, didnât you? Didnât you, you fucking whore?â
âNo!â I screamed, lunging forward and striking her hard round the face.
Which was when Luke punched me in the side of the head, knocking me down.
I cried out, hoping it would stop him from hurting me any more, but he pulled me to my feet by my hair and twisted an arm up behind my back.
At the same time Marla rushed into the kitchen, pulling open drawers until she found what she was looking for â a serrated chopping knife. She marched up to me and held the blade close to my face.
I tried to struggle free of Lukeâs grip but he pushed my arm even higher up my back, making me wail with the pain.
âAdmit you killed Crispin,â hissed Marla. âAdmit it now, or I will cut you into fucking pieces.â
âI didnât. I swear I didnât.â
She pressed the blade against my cheek and behind me I heard Lukeâs sharp intake of breath. I thought he was going to say something â tell her to calm down or something â but he didnât.
âPleaseâ¦â I was weeping now, unable to quite understand what was happening to me.
Marla stood there breathing heavily, her eyes full of rage, and I wondered whether or not she had it in her to carry out her threat. I wondered too whether she was actually the killer and was trying to put the blame on me, but that didnât make sense either.
And then I saw the faintest flicker of doubt cross her face, and she moved the knife away. âWeâve got to get rid of her,â she said to Luke. âI donât trust her.â
âLetâs lock her in the woodshed. Then we can get the fuck out of this place.â
âNo, please,â I begged.
But Luke was already marching me towards the back door, one hand pulling my head back by the hair, the other hand continuing to keep my arm right up my back. The pain was excruciating but still I tried to struggle, desperate not to be sent outside where I knew the killer lurked.
âDonât fight or Iâll break your fucking arm,â he hissed in my ear, pushing my arm even higher so it felt like it was going to snap. âOpen the door for me,â he told Marla, moving aside to let her through.
She unlocked the door and Luke dragged me out on to the back patio, manoeuvring me towards the woodshed.
I wasnât going in there. Not with Louiseâs rotting headless corpse, and where Iâd be at the mercy of the man who was intent on killing us all.
I couldnât. I had to survive.
Luke momentarily eased the pressure on my arm while he went to unbolt the shed door, and I thrust my free hand between his legs and grabbed his balls, twisting hard. He yelped in pain, his grip immediately slackening, and I pulled myself free.
âBitch!â he yelled, but I was already running.
He was quick to recover though, and I only just managed to throw open the side gate and run through it before I heard him right behind me. I accelerated, sprinting across the front lawn, heading for the safety of the trees. Except it wasnât safe. This was where Iâd seen Charlieâs ruined corpse. I desperately wanted to try to reason with Luke â to ask him why, if I was the killer, hadnât I murdered him and Marla when theyâd been fast asleep in the lounge? But I knew it was too late for that. He was only a yard or two away from me now, breathing heavily like an animal as he tried to run me down.
I hit the tree line, tore straight through a ragged tangle of brambles, ignoring the thorns as they slashed my skin.
