I arrived early at my sister’s house to get her surprise party ready, and I found the most disgusting scene of my life: her husband with her best friend in the bathtub. “Please don’t say anything,” he whispered to me. But I didn’t make a scene. I locked the door from the outside and dialed two numbers: my sister’s and that woman’s husband’s. When they arrived, all hell broke loose.

Suddenly, the muffled sound of running water drifted down from the second floor. I assumed it was Bridget’s husband, Garrett, taking a quick shower before he had to run errands for the celebration.

I decided it was a stroke of luck because I could coordinate with him on where the serving platters were stored without him being in my way downstairs. I climbed the stairs to give him a heads up that I was on site and to ask about the extra glassware.

Just as I reached for the handle of the master bathroom, the sound of a woman’s melodic laughter echoed through the door. It was a sharp, distinct sound that definitely did not belong to my sister.

A cold weight settled in the pit of my stomach as I pushed the door open just a few inches. My reality fractured instantly when I saw Garrett in the oversized soaking tub with Mallory, who had been Bridget’s inseparable best friend since their freshman year of college.

The scene was undeniable and lacked any possible innocent explanation. Garrett’s face turned a ghostly shade of white the moment our eyes met, while Mallory tried to sink deeper into the bubbles as if the water could hide her betrayal.
