Aiden’s Science Bridge Was Destroyed and Mason’s Shoe Seemed to Prove He Did It — Then the Classroom Camera Showed Who Planted the Evidence

Chapter 2 — Mason Had Been Trying to Help

Ms. Carter paused the video.

Aiden looked toward Mason.

“Why were you putting clay under my bridge?”

Mason looked embarrassed.

“Because it was rocking.”

“What?”

Mason explained.

He arrived early that morning to finish a geology display.

His project used brown modeling clay to demonstrate soil layers.

While walking past Aiden’s bridge, Mason noticed the front-left support wasn’t sitting flat.

The table itself was slightly uneven.

Every time someone walked past, the model trembled.

“I thought it might fall before you got here.”

So Mason tore off a tiny piece of clay.

Pressed it beneath the support.

Then tested the bridge gently.

“It stopped wobbling.”

Aiden stared at him.

“Why didn’t you tell me?”

Mason shrugged.

“I was going to.”

He looked toward the destroyed model.

“Then I walked in and saw this.”

Mason knew the clay on his shoe looked terrible.

He also knew he had been beside the model when nobody else was in the room.

That was why his first words had been:

“I didn’t touch it.”

Technically, he had touched it.

But only to keep it from falling.

Ms. Carter rewound the video.

“Look here.”

Mason’s clay support remained beneath the bridge when Chloe entered.

Without it, the model might have wobbled.

With it, the bridge was stable.

Chloe’s ladder strike caused the destruction.

There was no doubt.

Then Aiden remembered something.

“Chloe was here when we found it.”

Ms. Carter frowned.

“When?”

“Before you came in.”

Chloe had entered the classroom briefly.

She saw Aiden staring at the broken bridge.

Then said:

“I think Mason was in here earlier.”

At the time, Aiden barely registered the comment.

Now it sounded completely different.

Chloe hadn’t simply planted clay.

She had also planted the idea.
