It started with a simple, innocent question.
"Hey, did anyone use my toothbrush?" Claire asked, holding up her toothbrush as if it were an evidence exhibit at a court trial.
Everyone in the house was gathered in the kitchen, either nursing their morning coffee or halfway through a cereal bowl. Nobody said anything at first.
"I swear, I just got this yesterday," Claire continued, shaking the toothbrush in the air like it was a magic wand. "And it's already, like, three shades darker than when I bought it!"
Her little brother, Timmy, smirked from the corner of the room. "Maybe it's just your mouth," he said in a tone that made it clear he was holding in a laugh.
"I'm serious!" Claire declared. "Did anyone use my toothbrush for... anything other than brushing their teeth? Because it's suspiciously extra dirty."
A silence filled the room, thick and heavy like the air before a thunderstorm.
"Claire, nobody uses your toothbrush," her mom said, not even looking up from her coffee. "Why would anyone use your toothbrush?"
"I don't know!" Claire flung her hands in the air. "But look at it! It's covered in... something! And it's not toothpaste!" She looked at each of them, her eyes wide with an intensity that could only be explained by years of sibling rivalry and dental hygiene concern. "I have reason to believe someone's secretly using my toothbrush. I have to get to the bottom of this."
Her dad, who was flipping through the newspaper, muttered, "Could it be... your cat?"
Claire's eyes narrowed at him. "Dad, we don't have a cat."
Her brother Timmy burst out laughing, almost choking on his cereal. "It's probably Mom. She does the sneaky things. Like when she hides the cookies, but then says, 'Oh, they must have just disappeared!'" He mocked in a high-pitched voice, making exaggerated gestures.
"Timmy," their mom said, not even fazed. "That was one time. And you did eat all of them, so I had to hide them from you."
"Well," Claire continued, giving her family the kind of look that would've made even Sherlock Holmes sit up and take notes, "I'll get to the bottom of this. I'm conducting an investigation. No one leaves until I find the culprit."

The Investigation began. Claire's first move was simple: she set up a spy cam. Not a real one, but a makeshift camera—a jar of peanut butter sitting on the counter with the camera phone slightly peeking out from behind it.
She called it her "Peanut Cam." It was a work of art.
For the next few days, Claire watched the footage, analyzing every movement, every subtle shift in the kitchen. She studied her family members with the precision of an FBI agent, but after three days, she had come up with absolutely nothing—except for an unnerving amount of footage of Timmy raiding the pantry at 3 a.m.
"This is not helping," she grumbled, muttering to herself. "I need something... bigger."

The breakthrough came when Claire's friend Anna came over to hang out. Claire had just made herself a cup of tea when she noticed Anna giving the toothbrush a suspicious glance.
"I don't mean to freak you out," Anna said, "but I saw your brother using your toothbrush yesterday."
"WHAT?" Claire gasped, dropping her cup of tea in shock. "You're sure?"
Anna nodded. "Yeah, I thought it was weird, too. I didn't say anything because I didn't want to get involved in family drama... but I definitely saw him using it on his shoes."
"On his shoes?!" Claire shouted, incredulous.
"Yeah, he was scrubbing them down with it," Anna said, still looking casual, as though shoe-brushing with someone else's toothbrush was completely normal.
Claire's eyes widened. She couldn't believe it. Her brother, Timmy, had been brushing his sneakers with her toothbrush.

The next day, Claire confronted Timmy with all the evidence she had gathered, including the Peanut Cam footage and Anna's eyewitness account.
Timmy tried to act innocent at first. "I have no idea what you're talking about, Claire. I don't know what you're—"
Claire cut him off. "Don't lie to me, Timmy. We all know you used my toothbrush to scrub the soles of your sneakers like some kind of maniac!"
Timmy, now cornered, finally broke down in laughter. "Okay, fine! It was me! But you should've seen how clean they were after! And it worked way better than using a regular shoe cleaner."
Claire stared at him, mouth agape. "You used my toothbrush for shoes?"
"Yep," Timmy said proudly. "And honestly? It worked better than the store-bought stuff."
Claire's eyes twitched. "You know what? I'm buying a new toothbrush. And you can never touch it, or I will find a new place for you to sleep. And it won't be a bed."
Timmy's face went pale. "Okay, okay. I get it. You win."
Moral of the story? If your toothbrush mysteriously starts getting extra dirty... make sure to keep it away from everyone, also your sneakers, and any possible shoes in need of a good cleaning.
