Mercer Doss, sixty-one, rebuilt marine diesels in a shed that smelled of diesel and salt. His hands were scarred, his marriage over, his daughter grown. He liked engines because they told the truth.
The Biloxi Community Boathouse held a fundraiser on a humid Friday. Mercer went because his neighbor guilted him into it. String lights, a cash bar, a silent auction. He stood near the folding table, beer sweating in his fist, when a woman in a navy dress stopped beside him.

Her name was Tessa. Forty-nine, a harbor pilot, divorced. She smelled like citrus and engine grease, and she stood closer than strangers do. Her shoulder brushed his forearm when she reached for a pen. Neither moved.
“You’re the diesel guy,” she said. “My starboard engine’s been coughing.”
“They all cough,” Mercer said. “Some just hide it better.”
Her laugh was low and private. She held his eyes a beat too long, then looked away first. He felt it in his chest like a stuck valve.
They talked for an hour. She was sharp, funny, and direct. When a drunk councilman interrupted to press his hand to Tessa’s back, Mercer’s jaw tightened. She stepped neatly out of reach and stayed near Mercer’s shoulder the rest of the night.
Two weeks later she brought the boat in. She wore cutoffs and a tank top, hair tied back. Mercer climbed into the engine compartment, and she crouched beside him, close enough that her knee touched his hip. He felt the heat of her through denim.
“Hand me the wrench,” he said. She did, fingers grazing his palm. He didn’t pull away.
The truth was ugly. Tessa was the daughter of the man who’d run Mercer’s old shop into the ground back in 2004, leaving him broke and bitter. He’d sworn off that whole family. But her laugh had landed in him like a stone in still water. Disgust and desire sat in his gut at the same time, and neither would leave.
He fixed the engine in silence. She paid in cash, lingered at the door, and said, “You’re not as mean as you look.” Then she left.
He thought about her for a week. Hated himself for it.
She came back on a Tuesday, rain drumming the roof. No boat. She stood in the shed doorway, soaked, and said, “I know who you are to my father. I know what he did.”
Mercer set down his socket wrench. “Then why are you here?”
“Because you’re the only honest man I’ve met in years.”
She crossed the concrete floor. He didn’t back up. Rain hammered the tin. She stopped a foot away, close enough that he could see the pulse in her throat. Her hand rose, hovered near his chest, and then she pressed her palm flat against his shirt. He covered her hand with his, rough fingers over smooth skin, and neither spoke. The silence was a held breath.
“This is a bad idea,” he said.
“Terrible,” she agreed, and kissed him.
He kissed her back. The rain kept falling, and Mercer Doss, sixty-one, stopped rebuilding engines for the night.
