This is my first fanfic on here, I hope you enjoy it! and please review!

Unfortunately I do not own Castle.

They were in an alley. The exact alley her mother was killed in actually. A shot rang out and Castle sped around the corner to see his girlfriend of 3 years, Kate Beckett, fall to the ground. The suspect saw him and ran; Ryan and Esposito rounded the corner and hurried after the guy. Castle ran to Beckett's side, "Kate!" She had been shot in the abdomen. He held her in his arms and put pressure on the wound. "Rick" she said weakly,

"I'm here Kate, everything will be alright. I promise"

"Rick, kiss me" she said with a small smile. He complied and kissed her lightly but with so much passion. For a minute the world stopped. All her pain just disappeared. He had that affect on her. He would have been her one and done, she knew it.

"I love you so much" he murmured against her lips.

"I love you so much too" she whispered,

"I should have stopped him Kate; I should have stayed with you"

"Shhh" she touched his cheek with her hand. Her skin was as cold as ice; she was starting to fade,

"It's not your fault Rick, you didn't know… you… didn't… know…" her hand went limp and fell from its spot on his face.

"KATE! No! Kate! Stay with me! Please! I need you!" tears were streaming down his face. "Kate…" he said helplessly, "I love you" he whispered softly. He kissed her forehead and laid her down on the ground, he heard sirens in the background. A little too late, he thought.

He saw the suspect run by the alley; Kate's gun was just laying there next to her lifeless body. He grabbed her gun and chased after him. He cornered him; Rick wasn't scared, he was furious. "You son of a bitch!" he yelled, "You killed her! She was the love of my life! And you took her from me!"

Rick was starting to break down; he held up the gun with shaking hands and shot the suspect several times. Ryan and Esposito ran to see what was going on. Ryan placed a hand on Castle shoulder, "It's over Castle"

"Castle... Castle! Rick!" it was Kate, but how was she calling him… she was… Gone…

It's really short, sorry. Please review!
