The aroma of freshly brewed coffee, a luxury in Sarah's current life, filled the air as she waited. Her phone vibrated: Liam's text. "Be there in 5!" A grin stretched across her face, almost splitting her cheeks. She pictured his face, the smug little smirk he always had, the air of self-importance he adopted when he spoke of his "high-powered" job at a prestigious law firm. Today, she'd find out if the facade held.

She'd followed him that morning, hidden behind a towering oak tree across the street from the address he’d given her. His usual suit was exchanged for… well, nothing. He emerged, bare-chested from a dilapidated building, flexing his biceps and giving a thumbs up to a man who looked like he’d been sleeping in a dumpster. This was going to be good.

"Hey!" Liam's voice boomed from behind her. He'd somehow managed to change into his usual attire. "Ready for lunch?" Sarah turned, her eyes twinkling. "Absolutely." She linked her arm through his, her laughter bubbling up in her chest. "Just thinking about that big case you're working on! Tell me all about it!"
