I Only Wanted to Warn My Neighbor for Trespassing in Our Pool — Then I Realized I Grabbed a Banned Compound

The second Sandra Collins started screaming, every ounce of anger left my body.

Thirty seconds earlier, I had been furious.

Furious enough to do something stupid.

My name is Caleb Morrison.

I was forty-six that summer, living with my wife, Amy, and our two children in a quiet neighborhood outside Louisville, Kentucky.

Our backyard pool was supposed to be the peaceful part of the house.

Instead, it became the place where I nearly learned the worst lesson of my life.

Sandra stood waist-deep in the shallow end.

Cloudy water curled away from her legs.

She stared at me.

“What did you put in here?”

I looked down at the plastic bottle in my hand.

“I thought it was dye.”

“You thought?”

“Sandra, get out.”

She moved toward the steps.

Then stopped.

Her eyes were wide.

“You did this on purpose.”

“No.”

“You threatened me.”

“With harmless pool dye.”

“You poured something into the water!”

“I know.”

I turned the container around.

Then I saw the warning label.

My stomach dropped.

This was not the temporary color product I had purchased.

It was a restricted commercial compound that should never have been stored with ordinary residential pool supplies.

I had no idea how it got there.

“Get out now.”

Sandra climbed onto the patio.

I called emergency services before she could say another word.

I followed every instruction the dispatcher gave me.

Rinse.

Stay away from the water.

Do not touch the container again.

Keep everyone away from the pool.

Sandra wrapped herself in a towel, shaking.

“You wanted this.”

“I didn’t.”

“You’ve been waiting for an excuse.”

“No.”

“You told me you were going to teach me a lesson.”

That part was true.

And suddenly, every stupid word I had said over the previous two weeks sounded like evidence against me.

Then I noticed the handwriting on the bottle.

Black marker.

Not factory printing.

Three letters and a number.

R.S. — 14

I stared.

I had never written that.

Amy had never written that.

None of our pool supplies were marked by hand.

The harmless dye I intended to use had a bright green sticker around the cap.

This bottle had no sticker.

I turned toward the pool shed.

The door was open.

I had left it closed.

Inside, on the second shelf, was the actual bottle of temporary dye.

Unopened.

Exactly where I remembered placing it.

I looked from the dye to the container beside my foot.

Then toward the small security camera mounted beneath the garage roof.

Sandra followed my eyes.

“What?”

I said nothing.

“What are you looking at?”

“Somebody’s been in my shed.”

Sandra laughed bitterly.

“Sure.”

“I’m serious.”

“You poisoned the water and now somebody magically switched the bottle?”

“I didn’t say that.”

“You’re thinking it.”

I was.

And fifteen minutes later, the security footage showed I was right.

Someone had entered my backyard before sunrise.

Someone who knew exactly where my pool supplies were kept.

Someone who had spent less than four minutes inside the shed.

And when I saw his face, the bottle stopped being only about Sandra’s trespassing.

Because the man in the video was not a stranger.

Sandra knew him.

In fact, she had been trying to avoid him for weeks.

Sandra Collins had been a problem almost from the day we moved in.

Not a dangerous problem.

An irritating one.

She lived two houses behind us.

Fifty-eight.

Recently divorced.

Loud laugh.

Always wore oversized sunglasses.

Always knew everybody’s business.

When Amy and I bought the house, Sandra appeared on our porch the second afternoon carrying a bottle of wine.

“Welcome to Hawthorne Ridge.”

She smiled.

“I’m basically the unofficial neighborhood historian.”

Amy smiled politely.

“That sounds dangerous.”

Sandra laughed.

Then looked past us.

“You kept the pool.”

I remember the sentence because it sounded strange.

“Kept it?”

“The previous owners talked about filling it in.”

I shrugged.

“Our kids would never forgive us.”

Sandra nodded.

“Good.”

She took another look toward the backyard.

“I used to swim there all the time.”

That should have been my warning.

Instead, I assumed she meant she had been invited.

For the first month, nothing happened.

Then one Tuesday afternoon, I came home early from an appointment.

My thirteen-year-old daughter, Ellie, was still at school.

My ten-year-old son, Jordan, was at Amy’s mother’s house.

Amy was working.

I walked into the kitchen.

Through the sliding glass door, I saw someone floating in our pool.

Sandra.

She wore a red swimsuit.

A plastic cup rested beside the edge.

Her towel lay across one of our patio chairs.

I opened the door.

“Sandra?”

She lifted her sunglasses.

“Oh.”

I stared.

“What are you doing?”

“Swimming.”

“I can see that.”

She smiled.

“Beautiful afternoon.”

“Did Amy invite you?”

“No.”

“Then why are you in our pool?”

Sandra laughed like I had asked why she was standing on a public sidewalk.

“The Daltons always let me swim.”

“The Daltons sold us the house.”

“I know.”
