After wrapping up a high-stakes deal ahead of schedule in New York, Madeline Carter caught the first red-eye back to Austin, Texas. All she wanted now was to crawl into bed next to her husband, Ethan, and finally breathe. It had been a grueling month apart.

The house was dark when she arrived, the only light coming from the moon spilling through the windows. Madeline crept quietly through the front door, slipped off her heels, and tiptoed to the bedroom, excited to surprise Ethan in the morning.

But what she found stopped her cold.

There, on her side of the bed, was a baby. Fast asleep, nestled in a blanket, with a pillow propped beside him to keep him from rolling off. Ethan lay snoring softly beside the child.

She and Ethan didn’t have children. Never tried. So where had this baby come from?

Eyes wide, she shook her husband’s arm. “Ethan. Wake up. Now.”

He stirred groggily. “Maddie…? What are you—You’re home early.”

She snapped. “Whose baby is that, Ethan?”

He rubbed his face, yawning. “I don’t know exactly. Someone left him at our doorstep a few days ago. I didn’t know what else to do. I’ve been taking care of him.”

“What? Why didn’t you call the police?”

“I meant to,” he muttered. “But everything happened so fast. And then I started bonding with him. Look, I know this sounds insane, but I was going to tell you. I just… didn’t want to distract you during your trip.”

She reluctantly followed Ethan back to the bedroom. The baby was still sleeping peacefully. Despite everything, Madeline lay down beside him and, to her surprise, quickly drifted off.

At 7 a.m., everything changed.

Muffled voices woke her. She reached for Ethan—gone. The baby was gone too. Cautiously, she crept toward the living room, stopping just short of the doorframe when she heard a woman’s voice.

“Ethan, you have to tell her. This can’t stay a secret.”

“I know,” Ethan whispered. “I just… I want to wait for the DNA test.”

Madeline’s stomach dropped.

DNA test? Is this woman the baby’s mother? Did Ethan cheat on me?
