A figure dressed all in black and wearing a ski mask came out of the shadows of the night and rushed toward her.

It took Suzanna a moment to realize what was going on. The person reached her, and it was then Suzanna saw the flash of the large knife the person held.

The attacker slashed out at Suzanna. She instinctively raised an arm in defense. The knife sliced into her arm and it was then Suzanna screamed. Adrenaline rushed through her as terror gripped her heart…her very soul.

The person stabbed the knife out once again, a jab toward the stomach. Suzanna dodged it just in time. She was trapped against the side of her car with no weapon to defend herself with and no way to escape.

She screamed as the knife slashed out once again. It sliced her arm a second time. The two wounds burned and throbbed and began to bleed profusely. She continued to dodge and weave to keep the knife from stabbing her in a vital area of her body.

She knew her screams wouldn’t help her any. Her nearest neighbor was too far away to hear her cries for help. There was no question the person intended to kill her, and eventually the knife was going to do just that.

Tears of abject fear blurred her vision. She kicked and punched at the attacker, all the while dodging the vicious thrusts of the sharp weapon. The car. Her purse was still on the front seat, so if she could just get back inside it and lock the doors then surely she would be safe.

Rory stepped past the screen door, let it slam behind her. “What will you do, Ronnie? Kill me? Is that what you believe Pete would want you to do?”

“Don’t even say his name,” Cade growled. “You lost that right when you murdered him.”

Rory flinched. “Well, we agree on one thing.” She stared the former high school football star in the eyes. “He was murdered all right, but it was a couple of guys—like the two of you—who did it.” She looked from one to the other. “Maybe even friends of his.”

Fury whipped across Cade’s face. “You better watch your mouth—that kind of thing can get you dead.” Her heart pounded so hard she could barely breathe… but that beating in her chest was the only thing that told her she was alive anymore.

Otherwise, she had died two years, one month and four days ago…the same night asher husband. The husband she did not…would not…could not have hurt, much less murdered.

“Don’t waste your time,” she said, the bravado draining away, defeat taking its place. “I’m already dead.”

She turned her back on the two and went inside. She didn’t even lock the door. What was the point? If those two wanted to storm her house, she couldn’t stop them. Maybe she wouldn’t even try.
