The shelves were always crowded with products, and quiet conversations floated through the aisles throughout the day.

With her brown hair tied neatly in a ponytail and her friendly smile, Emily knew most customers by name—and often by their usual health complaints as well.

She was naturally observant. It was a habit that sometimes felt like a gift and sometimes like a burden, because it made her notice details others ignored.

And then there was Caleb.

Caleb lived a few blocks away in an old, fading house that always seemed covered in shadow. Emily saw him almost every day. But he never bought medicine, vitamins, or even cough drops.

He always bought the same thing.

Large packs of wet wipes.

Every day.

Sometimes even twice in one day.

At first Emily shrugged it off. Everyone had strange habits, and it wasn’t her place to judge.

But recently something about Caleb had changed.

He looked thinner than before. His clothes, once simply messy, were now worn and stained. Dark circles had sunk beneath his eyes, and his beard had grown wild and gray. He carried himself like someone who hadn’t slept in days.

And there was something else.

A faint metallic smell clung to him. At first it was subtle, almost impossible to notice. But lately it had grown stronger—a stale scent like rust… or something worse.

Emily tried convincing herself she was imagining things. But the question kept returning to her mind.

Why would a man who lived alone need so many wet wipes?

One Tuesday afternoon the pharmacy was nearly empty. Only the quiet hum of refrigerators and a soft radio played in the background.

Caleb stepped inside, hunched and silent. As usual, he walked straight to the shelf, grabbed the biggest pack of wipes, and brought it to the counter.

Emily smiled politely, though unease twisted in her stomach.

When Caleb reached out to pay with loose coins, his sleeve slipped back slightly.

And Emily saw it.

A dark stain on his wrist.

It looked like dried blood.

Not fresh—but brown and soaked into both his skin and shirt.

Her heart began pounding.

Blood?

The thought echoed loudly in her mind.

Caleb seemed to sense her staring. He quickly pulled down his sleeve, gathered his change, muttered a quiet “thanks,” and hurried out of the store.

The metallic smell lingered after he left.

That night Emily couldn’t sleep.
