Chapter 3: The Digital Vault
The living room smelled faintly of lemon furniture polish and old paper. Arthur sat at the heavy oak dining table, the morning sun casting sharp, angular shadows across the polished wood. In front of him lay the family tablet, its screen dark until Arthur tapped it with a steady finger. The security app icon stared back at him—a simple blue shield with a white checkmark.
Sarah stood behind him, her hands resting lightly on his shoulders, her fingers kneading the tense muscles at the base of his neck. Robert and Helen sat across the table, watching the screen with the tense stillness of spectators waiting for a verdict in a courtroom. Lily was in the next room, occupied with a quiet puzzle, her soft humming drifting faintly through the open archway.
“Enter the master PIN,” Sarah prompted quietly, breaking the silence that had stretched unbroken for ten minutes.
Arthur punched the four-digit code into the glass screen. The interface loaded with a faint digital chime, bringing up the home dashboard. Thumbnail feeds from the kitchen, the back patio, and the main hallway blinked into view. The thumbnail for the hallway camera showed the exact stretch of wall and doorway where the incident had occurred earlier that day.
“Go to the event history,” Helen urged, leaning forward so sharply her gray hair swayed. “Look at the timestamp right before Lily started screaming.”
Arthur swiped down, accessing the cloud playback logs. The software organized clips by motion detection events. There were dozens of entries from the past twenty-four hours: the cat walking past at midnight, Sarah carrying groceries in at noon, Arthur leaving for his morning jog. But as his finger scrolled down to the afternoon log, a strange anomaly appeared.
“That’s odd,” Arthur murmured, his brow furrowing as he stared at the screen.
“What is it?” Sarah asked, leaning in closer, her cheek brushing against his dark brown hair.
“There’s a gap,” Arthur said, pointing to the timeline. “The system logs show constant motion tracking, but right between two-fifteen and two-twenty, the clip is marked with an encryption tag. It didn't overwrite, and it didn't save to the local loop. It locked.”
Robert grunted softly, leaning back in his chair. “Locked files usually mean one of two things. Either the unit experienced a severe network drop and saved an error cache, or someone with administrator privileges triggered a manual bookmark.”
Arthur looked up from the tablet, locking eyes with his father-in-law. “I didn’t bookmark anything. I was in the middle of folding laundry.”
“Neither did I,” Sarah added immediately, her voice steady, though a flicker of unease crossed her features.

“Then who did?” Helen asked, her voice dropping to a whisper that seemed to echo off the walls.
Arthur stared back down at the tablet. The locked file sat there on the screen like a digital monolith, daring them to press play. The timestamp matched the exact window of time before Lily’s meltdown—the time Arthur could not fully recall. With a dry throat and a slow, measured breath, Arthur raised his hand and pressed the play icon.
