Seer Frights #11
Locker 237. End of the hall. Slightly misaligned. Colder to the touch.
No student lasts a week.
Three kids investigate and discover the custodian rigged the locker with a vibration trigger to scare off vandals and protect stored maintenance supplies. Simple. Clever. Explained.
But after the locker is permanently sealed shut, new scratches appear inside the metal door — visible the next morning through the ventilation slats.
The custodian didn’t put those there. The vibration trigger was removed. The locker is empty. And something is scratching from the inside.
Each Seer Frights book hides real, buildable electronics projects in the story. Field Notes at the back show you how.
. . .
Riley Thompson has had three lockers in six weeks. Two were full. One is haunted.
Locker 237 is the one at the end of the east wing, past the sealed fire door, under the fluorescent that flickers on a cycle nobody can fix. Riley is methodical — they document. When the locker vibrates, they note the time. When the combination changes, they write down what it changed to. Fear becomes data. Data becomes control.
Sofia Alvarez runs The Roosevelt Record (89 followers, aspiring). She interviews on instinct. Marcus Lee builds circuits in his garage and believes every strange thing in the world is a machine he hasn’t reverse-engineered yet.
Together, they crack it. Mr. Hines, the head custodian, rigged Locker 237 five years ago — a vibration motor, an electromagnetic override, a false back panel hiding the expensive HVAC parts that kept disappearing from the official supply room. Not malice. Just a guy protecting his tools with a homemade security system and a reputation for ghosts.
Sofia publishes the story. It goes semi-viral. Mr. Hines is suspended. The school board schedules the east wing locker decommission for winter break. Fourteen school days until the whole wall gets cut out and hauled to the recycler.
Marcus can explain the vibration. The cold air. The electromagnetic override. The combination reset. All of it.
He cannot explain the scratches.
They appear on the inside of the metal door after the locker is welded shut. Visible only through the ventilation slats. New ones each morning. The custodian’s system is gone. The locker is empty. The door hasn’t been opened.
And the scratches spell a name.
12. New student, mid-year transfer. Assigned Locker 237 because it’s the only one available. When scared, Riley over-researches — Googling symptoms, reading forums, building a case file. The locker is the first thing at Roosevelt that’s theirs. Losing it means losing the one anchor they have.
12. Runs the school blog, The Roosevelt Record. 89 followers. Aspiring journalist with a voice-recorder app and a habit of asking questions that make adults uncomfortable. Sees Locker 237 as a feature piece before she sees it as a threat.
12. Electronics hobbyist. Grew up soldering before he could read. If there’s a vibration, he measures the frequency. If there’s a cold spot, he checks the HVAC duct. Everything is a system. Everything has a circuit. Until it doesn’t.
58. Head custodian at Roosevelt for 27 years. The 80% explanation — the man who built the vibration motor, the electromagnetic override, the false back panel. Not malicious. Just a guy protecting his tools with a homemade security system and a reputation for ghosts.
Smart scares. Real engineering. Every Seer Frights book hides a working device inside the story. Field Notes at the end show you how to build it. Stephen King lite. Beyond Goosebumps but not quite IT.
