A Detective and a Middle School Student Work Together to Defeat Lupin

The following morning, Bramantara's house felt heavier than before. News of Aruna's disappearance spread through the secluded neighborhood, spiced with wild rumors that obscured the truth. The police had given up, deeming it a simple runaway case. But Rose and I knew it was more than that. The scent of the Bramantara family's despair pierced to the bone.

"There are no signs of forced entry," I told Rose, as we re-examined Aruna's silent room. The tightly drawn window curtains, the thin layer of dust on the sill, all indicated that no one had entered or exited from there. "This room was locked from the inside. So were the windows."

Rose observed every detail, her eyes narrowed. "This isn't a physical disappearance, Arez. This is more about the mind." She pointed to the riddle left behind earlier. "'Silent walls and empty mirrors.' These walls don't speak, the mirror in Aruna's bathroom indeed showed nothing strange. But the message might be a metaphor. Something that should 'speak' but is silenced, or something that should 'reflect' but is empty."

I felt the pressure to process every piece of information. My brain spun through all possibilities. I tried to connect Aruna's worn bunny doll, the children's storybooks on the desk, and the locked diary. Everything felt interconnected, yet difficult to unravel.

"'Time spins, but never moves forward.'" Rose continued, quoting the message. "This isn't a wall clock, Arez. This is about cycles, about repetition, or perhaps someone trapped in the past." She glanced at the small, locked diary on Aruna's desk. "And 'A soul imprisoned in illusion, can only hear the melody of darkness.' Aruna isn't gone. She's somewhere, trapped in an illusion created by someone."

My mind raced. If this was an illusion, who could create it? And why? I tried to imagine myself in Aruna's position. What could make someone believe they were somewhere else when they weren't? Hypnosis? Hallucinogenic gas? Or something more subtle and sinister? This was a challenge to understand the motive behind psychological manipulation.

"That painting..." I shifted to Aruna's painting in the living room. The empty eyes and the suddenly appearing music box. "Daisy said they sometimes hear whispers from it. A strange melody."

Rose nodded. "That's the key point, Arez. That painting isn't just a work of art. It's a portal, a medium. And the music box in Aruna's hand in the painting... that's something she never owned. A misplaced element."

We began to investigate deeper. I tried to talk to Bramantara and Daisy, asking them for every detail about Aruna, her habits, her friends, even dreams she had shared. Bramantara, still in shock, could only provide limited information, while Daisy seemed to sink deeper into despair. It was incredibly difficult to get information from them, being so emotionally fragile. I had to carefully phrase every question so as not to worsen their state.

"Aruna loved classical music, especially old melodies," Bramantara said, his voice hoarse. "She often played the piano."

Piano! "Melody of darkness." I remembered that phrase. Perhaps it wasn't a scary melody, but a melody that was silenced or twisted into something dark. I started connecting all the information. Classical music, the music box in the painting, the melody of darkness, and the whispers from the painting.

Rose invited me to look through the Bramantara family's mini-library. Shelves full of old books, some about music history and art. I found an open music notebook, with some handwritten musical notation. I compared it to the strange musical notation from the previous riddle. There were some similarities, but also many differences. This was a trap. "A melody without rhyme."

"Three keys, one answer, within the whispers of a dream." Rose murmured that sentence. "We have the locked diary. That might be one of the keys. But the other two?"

I thought hard. Three keys. In a dream. Did this mean we had to understand Aruna's subconscious? Or the mastermind's subconscious? This was a riddle that required us to delve into the mind.

"Try to notice every subtle change in the painting," Rose suggested. "Small changes can be big clues."

We observed the painting again. Aruna's empty eyes, the music box from nowhere. I touched the painting. Cold. Suddenly, I felt something uneven on the canvas behind the painted music box. I ran my hand over it. There was a slight bulge.

"Rose, look at this!" I pointed. Rose came closer. We both carefully felt the bulge. It was as if something was hidden behind it.

"The door opens, yet there is no way out. Shadows dance, where truth is silenced." Rose read the riddle again. "This isn't about a physical door, Arez. This is about making the wrong choice, about a mental trap. And those 'dancing shadows'... they might be illusions that make Aruna think she's somewhere, when she's not."

I began to form new hypotheses. This mastermind might be using auditory or visual illusions to manipulate Aruna. Perhaps they exploited Aruna's hidden traumas or fears. Or even made Aruna believe she was inside the painting itself. An illogical idea, but in this context, it might be possible. I had to consider all possibilities, even the most absurd. This was a mind game.

"I have an idea," Rose said, her eyes gleaming. "We need to enter Aruna's mind. Through the whispers of her dream."

I looked at her. "How?"

"There are several ways. But we have to understand what Aruna saw, heard, and felt before she 'disappeared.' And we have to find what those three keys represent. This is a game that requires a deep understanding of human psychology, Arez. More than just physical riddles." Rose glanced at the painting again. "And I think the key to the answer is there. Inside that painting."

We were still far from a conclusion. The air in this house felt increasingly cold. The shadows of the trees outside seemed to dance to the rhythm of an unseen melody of darkness. This mystery felt like an endless labyrinth, and I had to find a way out before Aruna truly vanished into the unreachable darkness. We could only continue to observe, piece together the puzzle, and try to predict the next move of this invisible mastermind.
