The Chicago chill of late November could freeze even the most resilient souls. But for David Mitchell, the cold outside was nothing compared to the gaping emptiness in his chest.

David, 42, a former police detective, sat silently in his dimly lit living room. The only light came from the bright red digital clock on the TV stand: 2:15 AM.

In his hand was a short-barreled revolver, its magazine fully loaded.

Today marked the fifth anniversary of the tragedy. Exactly five years ago, a drunk driver ran a red light, crashing into his family’s car. His wife, Sarah, and their two-year-old daughter, Chloe, were gone forever. The forensic report recorded Chloe’s exact time of death as 2:17 AM.

Since that day, David has died with them. He lived like a soulless corpse, drowning in alcohol and tormented by the fact that he had worked overtime that night instead of driving his wife and children home. Tonight, he decided to end it all. He would pull the trigger at exactly 2:17 AM, the moment his little angel’s heart stopped beating, so he could be reunited with his family in another world.

The clock ticked: 2:16 AM.

David closed his eyes. He raised the gun barrel to his temple. The cold metal against his skin sent a shiver down his spine. He began counting down the final seconds of his life. Ten… nine… eight…

Ring… Ring… Ring…

A jarring, ear-splitting sound suddenly shattered the silence of the house. It was the old landline phone in the corner of the room – the one David hadn’t used in years but hadn’t canceled. No one called this number at over two in the morning.

David ignored it. He gently squeezed the trigger.

Ring… Ring… Ring…

The ringing sound was like a life desperately struggling. The clock struck 2:17 AM.

At that fateful moment, instead of pulling the trigger, some invisible instinct – perhaps the training of a former police officer – made David lower his gun. He stepped forward, picked up the receiver, intending to yell at the intruder and end his own life.

“Who is it?!” David growled.

The other end was silent for a second, then a voice spoke. It was a thin, trembling whisper, choked with fear. The voice of a little girl.

“Uncle… are you Angel?”

The Call of Life

David frowned, half-drunk. “You’ve dialed the wrong number, little girl. This isn’t…”

“Please don’t hang up!” The child’s voice was panicked, sobbing. “My name is Lily. I’m seven years old. My mom said if one day she can’t protect me, if a monster appears… call this number. She said it’s the Guardian Angel’s number.”

David’s blood began to rush through his veins. He heard the little girl’s gasping breaths, and from the distance, through the receiver, the sound of things being smashed and the guttural curses of a man.

“Lily, listen to me,” his detective instincts kicked in, dispelling David’s suicidal thoughts. The gun in his hand suddenly found another purpose. “Where are you? What’s happening?”

“There’s a bad man… he broke the window. He beat my mom until she bled profusely. She’s lying unconscious in the kitchen. I’m hiding in the closet,” Lily sobbed, trying to keep her voice low. “He’s rummaging through things and calling my name. Oh, Guardian Angel… I’m so scared.”

“Lily, you must remain absolutely silent. Give me your address. Immediately!”

“Number 412, Elmwood Road… Ah!”

Heavy footsteps echoed through the speaker. The man had entered the bedroom.

“Where are you hiding, you little brat? Do you think you can get away with this?!” The man snarled right into the phone.

David froze. Number 412 Elmwood Road. It was only four blocks from his house! If he called 911 now, it would take the patrol at least ten minutes to get there because of the heavy snowfall. Ten minutes was more than enough time for a tragedy to occur.

“Lily, throw the phone under the bed and cover your mouth. I’m coming!”

David threw down the phone, grabbed his leather jacket and keys. He dashed out the door and jumped into his Ford pickup truck. The wheels screeched on the icy pavement, tearing through the silent night of the Chicago suburbs.

The Battle in the Snowy Night

The pickup truck screeched to a halt in front of the snow-covered lawn of 412. The oak front door had been smashed.

David drew his short-barreled revolver from his belt and moved like a ghost across the porch. Entering the living room, he saw a woman lying unconscious in a pool of blood.

He didn’t have time to check her breathing. Lily’s screams from the second floor ripped through his eardrums.

David rushed up the stairs like a wild beast. The bedroom door was wide open. A tattooed man, clutching a blood-stained dagger, was dragging a little girl out of the closet. Lily struggled, screaming in desperation.

“Put her down!” David roared, pointing the gun directly at the man’s head.

The criminal recoiled in shock. Seeing the dark muzzle of the gun and the murderous intent in David’s eyes, he panicked and released his grip on the little girl. But the ruthlessness of a desperate man drove him to lunge at David, raising the knife to stab him.

David didn’t flinch. He dodged to the side with the speed of a seasoned detective. With a decisive movement, he struck the man on the back of the neck with the butt of his gun. The criminal collapsed to the floor like a felled tree, unconscious.

David immediately kicked the knife away, pulled a plastic cable tie from his jacket pocket, and bound the man’s hands behind his back. At the same time, the sirens of police cars – which David had called on his cell phone while driving – began to blare from the end of the street.

Everything was safe.

David holstered his gun and quickly knelt down beside the little girl huddled in the corner. He took off his leather jacket and draped it over Lily’s small, trembling body.

“It’s alright, Lily. I’m here. You’re safe,” David gently stroked her hair.

Lily looked up at the large man in front of her with her big, teary eyes. She wrapped her thin arms around his neck, sobbing. “You’re an angel… My mother didn’t lie…”

The Twist Under the Emergency Lights
Fifteen minutes later, the house was filled with the flashing red and blue lights of police cars and ambulances. The criminal – identified as a burglar with a prior conviction – was handcuffed and taken away.

The woman – Lily’s mother, Evelyn – had regained consciousness after receiving first aid. She only suffered minor injuries and blood loss, nothing life-threatening. As she lay on the stretcher, her eyes met David’s, holding Lily’s hand, standing in the corner of the room.

Evelyn froze. Tears welled up in her eyes. Using her last ounce of strength, she asked the paramedics to stop the stretcher.

“Are…are you David Mitchell?” Evelyn whispered.

David frowned in surprise. “Yes. How do you know my name?”

Evelyn burst into sobs. She reached out her trembling hand, trying to grasp her benefactor’s sleeve.

“Five years ago…” Evelyn said, her voice breaking with emotion. “My Lily had end-stage congenital heart failure. She only had a few days to live. But on a cruel winter night, a miracle happened. The doctor announced a perfect match had just been donated.”

David’s heart skipped a beat. His breath caught in his throat.

“Organ donation laws keep identities confidential,” Evelyn sobbed. “But a nurse, feeling sorry for my daughter and me, secretly slipped a piece of paper into my hand. It had the landline number of the organ donor’s family on it. She said, ‘The child who saved your daughter’s life is only two years old. Her father just lost his entire family in a horrific accident tonight.'”

David’s world seemed to crumble, then be reborn in an instant. His eyes welled up with tears.

“For the past five years, I haven’t dared call you for fear of reopening such a painful wound for a father,” Evelyn continued, tears streaming down her face. “I just saved your number in my contacts, taught Lily to memorize it. I told her that the heart beating in her chest belongs to an angel. And this number… is the number of the one who gave birth to that angel. If one day she faces the brink of death, she should call this number to ask for his protection.”

And tonight, when the criminal cut the cell phone line, Lily used the old landline in her bedroom, trembling as she dialed the numbers her mother had made her memorize for years.

At exactly 2:17 a.m. The exact moment David raised the gun to his head, intending to commit suicide.

The Heartbeat of Rebirth
The stretcher slowly rolled Evelyn to the ambulance.

In the devastated living room, only David and little Lily remained. The 42-year-old man, weathered by the elements, who had once thought his life was nothing but a dark grave, now knelt on the floor.

He wept. Tears burst forth, overflowing with the pain, resentment, and despair that had been suppressed for five long years.

Lily stepped forward, using her tiny hand to wipe away his tears. She smiled, a radiant and warm smile like the first rays of sunlight dispelling the cold winter night.

“Don’t cry, little angel,” Lily whispered.

David trembled as he reached out, embracing Lily’s small body against his broad chest. He closed his eyes, pressing his ear against her left breast.

Through her thin sweater, a distinct sound echoed.

Thump… Thump… Thump…

A powerful heartbeat. Full of life.

It was Chloe’s heartbeat. His daughter’s heart had never stopped beating at 2:17 a.m. that year. It had simply transferred to another body, continuing to live, to love, and to grow day by day.

And then, five years later, at the fateful moment when the most desperate father was about to pull the trigger to end his own life, that very heart called out. It reached through the darkness of death, calling him to save its life once more, and at the same time… to save its own lost soul.

His mother.

Outside the window, Chicago’s worst snowstorm had stopped. The gray clouds gave way to a brilliant dawn, casting the first warm rays of light into the room.

David Mitchell tightened his embrace, holding little Lily. The cold gun had been tossed into a corner. Life had truly returned. For the first time in five years, David understood that he didn’t need to seek death to be reunited with his daughter. Because a part of her life was still right here, warm and resilient, beating with renewed rhythm, right in his arms.
