The Glass Wall Between Us

The lawyer sat across from me, his water glass sweating onto the mahogany table. "We need evidence," he said, and I thought about how strange it was that this stranger knew more about my marriage than I did.

I'd started as an amateur—a reluctant spy in my own life. At first, it was just checking his phone when he showered. Then came the keylogger, the GPS tracker clipped to his car's undercarriage. Each digital breadcrumb felt like a small betrayal, but necessary. Like removing a splinter.

"What about a friend?" I asked. "Someone on the inside."

He nodded. "If you know anyone he trusts implicitly."

I did. Sarah. She'd been my best friend since college, had stood beside me in a champagne-colored bridesmaid dress while I'd promised to love Richard forever. Now I would have to ask her to choose sides.

The first time I suspected Richard was cheating, I was cleaning his aquarium. The goldfish—orange and white, named Freckles—pressed its mouth against the glass, opening and closing in that eternal, silent begging. Richard used to stand there watching them for hours after work. Now he came home late, smelling of whiskey and someone else's perfume.

I called Sarah that night. We met for coffee, and I laid it all out—the tracking apps, the photographed receipts, the gnawing certainty that Richard was sleeping with his junior associate. Sarah's hand shook when she lifted her cup.

"That's awful," she said, but wouldn't meet my eyes.

"You'll help me?"

"Of course. You're my oldest friend."

Two weeks later, Sarah sent me a photo from inside his office: Richard and the junior associate, tangled together on his couch. I showed it to the lawyer. He nodded, satisfied.

"This is good," he said. "Very good."

I went home and fed the fish. Freckles swam to the surface, expecting food. I watched it dart behind the plastic castle, safe in its tiny transparent world. Better to live behind glass than to know what's watching from the other side.

Sarah stopped calling after the divorce was final. I didn't mind. Some betrayals are necessary, after all. And I'd learned that the worst kind of spy isn't the one who steals secrets—it's the one who was never really on your side at all.
