Chlorine and Alibis

I didn't mean to become a spy, but grief has a way of reshaping us.

After Marcus died, I started haunting places he loved. His racquet club became my morning ritual - I'd linger by the pool, nursing lukewarm coffee while gripping my vitamin D supplements. The doctor said I needed them for the bone-deep fatigue that settled in after the funeral. The padel courts became my observation deck, where I learned to read people through their movements.

That's when I saw her - the woman who now moved through his spaces like she belonged there.

She and Marcus had played padel together every Thursday for three years. I knew this because I'd found the engraved medal in his bedside table, tucked behind his vitamin bottles. She had precise, athletic movements. Her laugh carried across the courts like something she'd practiced.

I started swimming during her matches. The water drowned out their conversation, but I'd surface periodically, gasping, to watch them through distorted, chlorinated vision. Something in their ease together felt wrong - too practiced, too weighted. I found myself checking her phone when she left it unattended in the locker room, scrolling through months of texts that meant nothing until you rearranged them chronologically.

"Just checking her technique," I told myself, though my hands shook.

The detective who handled Marcus's car accident case thought I was having a breakdown. "Vitamin deficiency," he'd said, not unkindly, when I showed him the texts. "Grief does strange things."

But then came her Thursday morning breakdown on court 4. I watched from the pool as her partner - a stranger, not Marcus - placed a hand on her shoulder. She was weeping, not about backhands or scorekeeping. Through the water's warble, I heard my husband's name.

Later, dripping and shivering, I approached her. Her eyes were red-rimmed, defensive. She thought I was going to accuse her. Instead, I held out my hand.

"He was going to leave me," she whispered, the truth finally surfacing between us. "Thursday mornings were our goodbye tour. We were ending it."

Three years of Thursdays - an affair conducted in forty-five-minute intervals, bracketed by vitamin supplements and padel scores. They'd manufactured their end just as the car accident manufactured his.

Now I swim alone. The vitamins sit on my bathroom counter, untouched. Some days I still spy on her matches, noting how her movement has lost its precision, how she serves into the net like someone expecting to miss. Two women adrift in the same chlorinated water, neither of us certain whether we're swimming toward something or simply staying afloat.
