Chapter Two

Danny heard Grace's sudden intake of breath. Not daring to take his eyes away from the gun hovering just mere inches from his forehead, Danny did his best to block the man's view.

"You don't look well Detective Williams." The unmistakable thick Irish accent cut through the silence.

"Aidan." Danny held a hand up in an attempt to appease him. "What are you doing here?"

Taking a step forward he peered over Danny's shoulder to Grace. She stood, arms folded tightly across her chest. Trying desperately to stop the tremble coursing through her body, threatening to drop her to the floor. She could feel her heart thumping in her chest, and hear the blood rushing loudly in her ears.

Ignoring Danny's question, Aidan continued. "Didn't anyone tell you saving lives is bad for your health?"

Closing the gap between them, he pressed the cold metal of the barrel into Danny's forehead. Aidan smiled broadly.

"Oh...but you already know that, because I saved yours. And what thanks did I get? A few days in a coma, weeks in hospital, followed by months in a Federal Medical Center, courtesy of the FBI."

"What did you want me to do Aidan? You nearly killed me." Danny's voice remained calm, but on the inside his stomach twisted in fear. Not for himself, but for Grace.

"She looks scared." Aidan sneered sardonically as if reading Danny's mind.

"Leave my daughter out of this. Grace run to your room." Danny said, sounding harsher than he intended.

"No Grace. Stay where you are." Aidan shouted.

Grace visibly flinched at both their words.

Aidan jabbed the gun at Danny more forcefully this time. Danny stumbled backwards slightly, the wall and the crutch he leaned on the only reason he stayed upright.

"Please don't hurt my dad." Her voice broke on the last word.

Aidan now stood fully inside the door, kicking it shut behind him.

"Kneel down." Aidan ordered.

When Danny didn't respond immediately he pulled the crutch out from under him, causing Danny to fall heavily to the floor. Yelling out in pain as the impact jarred his ribs. Grace ran to his side. Kneeling down, she helped him sit up. Throwing the crutch down, Aidan seized her arm, pulling her to her feet.

"Go find me your dad's handcuffs."

Grace looked to her dad, on receiving a look of approval she ran off to his bedroom. She knew he kept them with his badge in the drawer by the bed. Running in the room she could hear them shouting. The venom in their voices scared her. She'd never heard her Danno like this, but she knew he was hurting and trying to protect her.

"So help me...touch her again -"

"Touch her again and what? You seem to forget I'm the one with the gun."

"What's this about Aidan? If you wanted a thank you, you should have just asked. You want the car? Is that it?"

"My brother's dead. Someone needs to pay."

"Why me? I didn't kill your brother."

"If you hadn't turned up that day. He'd still be alive."

"How'd you work that one out? Genius."

"What's taking your daughter so long?"

"Grace." Aidan bellowed.

She jumped on hearing her name. Opening the drawer, she reached in and picked up the handcuffs, hesitating when she saw what lay next to them. Alongside Danny's badge was his service revolver. He normally locked it away, but the events of the past few years had changed him. Starting with her kidnapping, he'd kept her closer, growing over-protective at times. Deep down she knew she wouldn't have it any other way.

She'd never held her dad's gun, it looked very much like Uncle Steve's. Now his gun she had held, and unbeknownst to her Danno, Uncle Steve had shown her how to use it.

"Don't make me hurt your dad. Get back in here now." Aidan yelled.

Grace slammed the drawer shut and ran out of the room.

Danny now knelt uncomfortably on the floor facing Aidan. He heard her rapid breaths behind him. Suddenly the room felt cold, a shiver ran down his spine. All the color had drained from Aidan's face and he just stared at a spot behind Danny. Of course Danny knew his daughter well, and he remembered the contents of his bedside drawer.

Not daring to look away from his antagonist, he swallowed hard to clear the lump that now lodged in his throat.

"Gracie baby. Put the gun down." His voice sounded hoarse.

The only response to his request, the unmistakable sound of the safety being clicked off.

Danny dropped his head to his chest and squeezed his eyes shut. Taking a deep breath he tried again.

"Please Grace...I'm begging you...put the gun down." Danny opened his eyes and looked over his shoulder at his daughter. She stood stock still, arms stretched out in front of her, hands tightly wrapped around his gun. His mind reeled. How the hell did she know how to hold it. She glared at Aidan, her face was pale, and her lips trembled as she tried not to cry. Danny's breath hitched, it felt like someone had reached in and ripped out his heart.

"Are you ready to play the hero again?" Aidan's voice was laced with bitterness.

In the split second it took to pull the trigger, Danny launched himself at Aidan, knocking him backwards to the ground. Unable to stop himself, Danny fell along with him, hearing two ear-splitting gunshots as he landed hard alongside Aidan. The weapon slid across the floor and out of reach. Aidan was the first to his feet. He picked it up and without hesitation fled the house.

Just minutes after climbing into bed, Steve's cell phone broke the silence in his room. Groping blindly in the dark he picked it up from the nightstand. Frowning at the number he didn't recognize, he answered gruffly.

"McGarrett."

"Sorry Commander." A female voice replied. "This is HPD dispatch. We've received a report that gunshots have been heard coming from Detective Williams home and we have been unable to contact him."

"I'm on my way."

Cutting the call, he immediately thumbed the speed dial for his partner. It went straight to voice-mail. While dressing he held the cell awkwardly between his ear and shoulder, now calling the rest of his team. He was in his truck before he'd finished the calls. Pulling out of the driveway he sped to his best friend's house. Again and again trying to raise him, but it always went to voice-mail. Every time it did, Steve slammed his hand into the steering wheel in frustration.

"Damn it Danny. What now?"

He pulled up to the curb, screeching to a stop. Suddenly the once quiet street was filled with the sound of police sirens. The rest of his team was not far behind.

Five-0 surveyed the scene in front of them. Danny's house. There was no movement, just the flickering light from the TV. Nothing else.

Steve took control, instructing HPD to create a perimeter and hold station. He knew time was of the essence; they needed to move fast and efficiently. Danny and Grace's lives could well depend on it. Pushing those thoughts to the back of his mind, he briefed the rest of his team and within minutes of arriving they were ready to move in. Wearing full tack gear, with their guns raised, they cautiously approached the house. The tension in the air was palpable. Steve took point, moving slowly along the drive past Danny's Camaro up to the front door. And that's when he heard it, that unmistakable voice. Grace.

H50 H50 H50 H50 H50

Danny watched in horror as Grace collapsed, the gun slipping from her grasp, and clattering to the floor. He scrambled across the room to where she lay. Fighting the all-encompassing pain that threatened to consume his body, he pulled her up into his arms. Feeling his touch she instantly grabbed onto him allowing herself to be pulled up onto his lap. Danny now sat legs outstretched, Grace positioned across them, her upper body leaning into him. She felt cold, her heart pounding rapidly against his chest. He tried to ignore the pain pulsating through his injured thigh and broken arm. They held onto each other as if their lives depended on it.

"I'm sorry." His chest muffled her voice.

He stroked her dark brown hair, rocking them both back and forth.

"Please don't leave me daddy. I love you." Hearing her weak trembling voice broke his heart.

"Monkey, I'll never leave you." Sobs racked his weakened body.

Huddled together on the floor, cocooned by his embrace, his familiar scent comforted her, made her feel safe. Tears rolled down her face and wet his t-shirt. The deep ache she felt in her heart was almost more than she could bear.

From somewhere in the room, his cell phone rang. She didn't recognized the first few callers, but the last one she knew. It was Danno's ring tone for Uncle Steve, the theme to Mission Impossible. The sound of it playing filled her with hope.

After what seemed like a lifetime, the distant sound of police sirens could be heard. Shortly followed by the screeching of car tires, doors slamming, and shouting. There was the unmistakable voice of her Uncle Steve.

Her dad's sobs had ceased moments before, his arms no longer squeezing her tightly. Untangling her body slowly from his grip. She gently lowered him to the floor. Making sure his head landed softly, not wanting to cause him any more pain. Pushing to her feet, she wiped the back of her bloody hand across her tear-streaked face. Padding softly, bare foot, to the door. Hand gripping the handle, she took a deep breath.

"It's me, Grace. I'm going to come out, Uncle Steve."

"It's alright Grace; I'm here." Steve's voice her undoing.

Opening the door, Grace stumbled forward, falling into his arms. Her next words froze him to his very core.

"I shot my Danno."
