Finishing the Puzzle of My Corpse

My mom? Didn't Zack say she died because a drunk driver hit her when she was out buying cake for me? How did drug dealers get involved in this?

I turned to look at Zack in disbelief.

"It's possible. After all, only heartless scums like drug dealers would do something this cruel!" His expression changed suddenly. "Shit! Madie is alone at home!"

Zack immediately dug out his phone.

Officer Wright turned to the others and said, "You all should quickly get in touch with your families too."

Zack made several calls, but no one picked up. He immediately started panicking, his hand began to tremble uncontrollably while holding the phone.

"No…No…surely nothing would happen to Madie!" he mumbled before turning to bolt out of the door.

Officer Wright hurriedly yelled, "Stop him!"

"Let me go!" Zack struggled desperately. Despite his thin frame, he managed to knock down three burly police officers.

"I'm going to look for my sister! Stop blocking my way!" He angrily pushed away those blocking him, eyes red.

I was stunned seeing how Zack was losing it. He wasn't this out of control even when Mom had her accident.

It turned out he cared a lot about Madison.

My chest felt unbearably tight as a deep ache settled within me.

At that moment, Zack's phone suddenly rang.

"Hello, Zack?" Madison's somewhat lazy tone came through, and he immediately relaxed.

After ending the call, Zack turned to apologize to the others. "Sorry, guys—I got a little carried away earlier."

I felt upset seeing how he'd calmed down once again.

I was also his sister. Why wasn't he worried about my whereabouts too?

I bit down on my lips, yet tears rolled down my cheeks.

At that moment, a police officer walked over. "We found more human remains, Officer Wright."

He then placed the black plastic bag on the autopsy table. As soon as it was opened, a foul stench of blood mixed with decay hit everyone.

Everyone couldn't help but frown in discomfort.

Zack was the only one who seemed like he didn't notice the smell at all, calmly taking the bones and chunks of flesh out of the bag.

After a good six hours, he finally stopped to look at Officer Wright. "This is probably the victim's entire body."

"Any new findings?" Officer Wright asked anxiously.

Hearing this, Zack's expression turned serious. "The victim is missing a kidney."

My breath caught upon hearing that I was missing a kidney.

I smiled bitterly. It wasn't missing at all—after all, it was inside Zack.

Back then, he developed kidney failure at a young age due to a hereditary condition. I managed to donate one of my kidneys to him in secret with Mom's help.

Zack completely lost it after learning the truth. He even held a knife against his neck, threatening the doctor to return the kidney to me.

I had to beg him not to hurt himself—or I would kill myself following him as well. Only then did he drop the knife.

Zack then hugged me tightly and cried. "I'm sorry, Sandy. It's all my fault—I never should've let you go through so much pain. That anesthesia shot must have hurt a lot! What would you do without a kidney now?"

Since then, he grew even more attentive and caring for me. That was the happiest moment in my life.

I wondered if Zack still remembered that.

At that moment, he seemed to have recalled something. His expression grew anxious when he said, "I know it now!"

My heart stopped for a moment. Did Zack finally realize that I was the one lying on the autopsy table now?
