The Night Billionaire Grant Mercer Chose His Mistress Over His Pregnant Wife, He Lost Far More Than the Empire He Had Spent His Life Building

By 4:00 AM, the digital ink on the Northstar acquisition was dry, and the celebratory after-party in the penthouse suite of the Halcyon Grand was winding down. The room was littered with crumpled napkins, empty caviar tins, and the heavy scent of expensive scotch.

Grant Mercer stood by floor-to-ceiling windows, looking out over the glittering skyline of Chicago. His phone, which had been resting silently on the marble bar, vibrated with a low, persistent hum.

He picked it up, expecting a text from his chief financial officer regarding the morning wire transfers. Instead, he saw three missed calls from an unknown number at Lakeshore Women’s Hospital, and a text notification preview that had somehow slipped through Celeste’s management: URGENT: PATIENT ADMISSION.

Grant frowned, a sudden, cold knot forming in his stomach. He looked around the suite. Celeste was fast asleep on the velvet sofa, her white satin gown pooled around her like spilled cream, her phone clutched in her hand even in slumber.

He walked down the private hallway to the master bedroom and dialed Natalie's cell phone.

It rang four times, then went straight to voicemail.

"Natalie," he said into the phone, his voice carrying the defensive edge he always used when he felt guilty. "It's me. Look, the acquisition went through. It was a madhouse down here. Call me when you get this so I know you're home from... wherever you went."

He hung up, feeling a vague irritation. Natalie always overdramatized things when she was stressed. It was a habit he had learned to tune out during their six years of marriage—years where he was building an empire from the ground up while she expected him to play the domestic partner.

He poured himself two fingers of scotch, swirling the amber liquid as he stared at his reflection in the dark glass. He had everything he had ever wanted. Four billion dollars in hotel assets. A seat at the global hospitality roundtable. A brilliant, stunning strategist who anticipated his every business move before he even made it.

So why did the glass feel so heavy in his hand?

A sharp knock at the penthouse door broke the silence. Grant frowned, checking his watch. It was four-thirty in the morning.

He walked to the foyer and pulled the heavy oak door open. Standing in the hallway was not a room service waiter or a hotel manager, but a middle-aged woman with tired eyes, wearing a tailored navy suit that looked like it had been slept in.

It was Rebecca Ellis, Natalie’s older sister, who had caught the first red-eye flight out of Atlanta upon receiving a call from Dr. Price.

"Rebecca," Grant said, stepping back in surprise. "What are you doing here? How did you even know which room—"

Rebecca didn't wait for an invitation. She stepped past him into the foyer, her eyes burning with a cold, devastating fury that made the billionaire step back.

"Where is she, Grant?" Rebecca's voice was deadly quiet.

"Where is who? Natalie?" Grant crossed his arms, his defensive armor instantly snapping back into place. "She went home hours ago. I've been trying to call her."

Rebecca stopped dead in her tracks, turned around, and looked at him as if he were a ghost. Then, slowly, a bitter, humorless laugh escaped her lips.
