The Sphinx of Court Four

The bull market had been generous to Marcus, but it had made him paranoid. He watched Elena from across the padel court, her movements precise and predatory, like she knew something he didn't.

They'd met at this club three years ago—she, the sphinx in tennis whites, smiling mysteriously at his terrible backhand. Now, as she smashed the ball past him for the third time, he found himself wondering: was she ever really his, or was she always watching?

"You're distracted," she said, tossing him a fresh ball. Her dark eyes held that same inscrutable quality that had drawn him in. The riddle of Elena Sokolov.

"Work," he lied.

But the truth sat heavy in his pocket: the encrypted drive he'd lifted from his firm's server room. Insider trading evidence. If the SEC found it, he'd lose everything. If his partners found he'd taken it, worse.

He'd thought he was being clever. Then last Tuesday, he'd noticed the ethernet cable running from their home office—Elena's workspace—snaking suspiciously toward the router's secondary port. A packet sniffer. She'd been monitoring his traffic.

A spy in his own bed.

"Marcus?" Elena stood at the net, waiting. The golden hour light caught the sweat on her collarbone. She looked like forgiveness personified. "Are we playing or not?"

He walked to the net, his heart hammering. "Elena. I know about the cable."

Her expression didn't change. She watched him with that ancient, sphinx-like patience.

"Why?"

"Your partners hired me, Marcus. Two years ago." She gestured vaguely at the luxury around them—the club, her designer gear, the life they'd built. "None of this is real. They wanted insurance."

"And now?"

"Now I'm supposed to report when you move the drive." She stepped closer, her voice dropping. "But I've also watched you cry at Pixar movies. I've seen you with your niece on Sundays. I know you're not the person they say you are."

She touched his arm, her fingers light.

"So what's it going to be, Marcus? Do you trust the spy who fell for the mark?"

The bull market crashed on Tuesday. Marcus turned state's witness, and Elena's report to his partners never arrived. Sometimes the most dangerous riddle is figuring out who's really playing for your side.
