Surface Tension

The pool was empty at 2 AM, which was exactly why Elena swam then. The water swallowed everything—the insomnia, the gnawing uncertainty, the constant vibration of her husband's phone on the nightstand while he pretended to sleep.

She'd been checking his messages for weeks. A spy in her own marriage, scrolling through encrypted apps and deleted threads, piecing together a timeline that made her stomach turn. The irony wasn't lost on her: she'd spent ten years as an intelligence analyst, and now she was using those same skills to dismantle her own life.

Barnaby, their elderly golden retriever, waited on the pool deck, his chin resting on his paws. He'd been her companion through the long deployments, the miscarriage, the years when work was the only thing that made sense. Now he watched her with eyes that seemed to understand everything.

Elena flipped onto her back, floating in the blue silence. The water held her like a second skin, weightless and whole. Down here, there were no secrets, no lies, no careful calculations about when to confront him with what she'd found.

"You're here again," a voice said from the deck.

Elena righted herself, treading water. A woman stood in the doorway—Sarah from marketing, the one whose name appeared in James's phone at 3 AM, 2:45 AM, 1:17 AM. She wasn't holding anything threatening. Just a gym bag, shoulders slumped.

"My husband," Elena said, swimming toward the edge. "He talks about you."

Sarah laughed, a broken sound. "He talks about you constantly. He's worried you're going to leave him. Says you've been distant, checking his phone, acting like you're waiting for the other shoe to drop."

Elena pulled herself out of the water, dripping and suddenly cold. "He's the one with the secret chats."

"We're planning your surprise anniversary party," Sarah said. "He's been frantic because he knows how you are with secrets. You notice everything. He was terrified you'd find out and ruin the surprise."

Barnaby lumbered over and pressed his wet nose against Elena's hand. She looked at Sarah—really looked at her—and saw the exhaustion of someone orchestrating joy for a person they'd never met.

"I'm an idiot," Elena said.

"You're a spy," Sarah said gently. "It's your job to suspect everything. But sometimes people really are just swimming because they can't sleep."

Elena sat beside her dog on the cold tile, the water dripping from her hair like the tears she couldn't seem to cry anymore. "He's going to be so relieved he's not being investigated."

"He's going to be terrified you found out about the party," Sarah said, sitting down beside her. "So we're both going to have to keep being spies."

Barnaby sighed, content with the arrangement. Some secrets were worth keeping.
