My husband’s obsession with cleaning the bathroom never made sense to me. Then my forensic pathologist friend spotted something I had overlooked for years.

Thirty seconds later, the quiet of the house was shattered.

It wasn’t a scream. A scream I could have rationalized as a spider or a slipped footing. Instead, it was my name, spoken in a hushed, breathless whisper that carried an arctic chill down the staircase.

“Natalie.”

I abandoned my coffee and hurried up the carpeted stairs. When I reached the top landing, I found Clare standing perfectly rigid just outside the bathroom threshold. All the natural warmth had been completely siphoned from her complexion. Her eyes were wide, fixed on the gleaming, spotless tiles.

“Clare? What is it? Are you sick?”

“Get out. Right now.”

“What?” I chuckled nervously, reaching out to touch her shoulder.

She flinched, her hand snapping out to snatch my wrist in a vice-like grip. Her fingers felt like they had been packed in ice. “Do not touch anything in this room, Natalie. Step back.”

A cold coil of dread tightened deep in my abdomen. Clare pulled me backward into the hallway, using her elbow to firmly push the bathroom door shut, intentionally avoiding the brass handle. She turned to me, her chest rising and falling in shallow, measured breaths.

Then, she asked a question that made absolutely no sense. “Has Ethan cleaned this room today?”

“No,” I stammered, rubbing my wrist. “He got a call. He rushed out early. Clare, you’re scaring me.”

She didn’t soothe me. She didn’t apologize. Instead, she reached into her pocket and retrieved her phone. “I need you to call the police, Nat.”

I stared at her, my mind stalling. “The police? Why would I call the police over a clean bathroom?”

Clare slowly turned her gaze back to the closed wooden door, her jaw clenched tight. “Because, Natalie, someone has been systematically cleaning up blood.”

A hysterical, bubbling laugh escaped my throat. It was a defense mechanism because the alternative was accepting the terrifying gravity in my best friend’s eyes.

“There isn’t any blood, Clare. The room is white. It’s practically a surgical ward. You’re being paranoid.”
