My Housekeeper’s Four-Year-Old Daughter Found a Hidden Key Under My Table—Then She Pointed at My Most Trusted Adviser.

By three in the morning, the mansion had returned to an uneasy quiet. Heavy security details patrolled every hallway, and extra guards had been posted along the perimeter gates.

In the second-floor master suite—which Roman had personally assigned to Megan and Sadie for their safety—the warm amber light of a bedside lamp illuminated the room.

Megan sat on the edge of the large king-sized bed, wearing a soft gray sweater and leggings. She watched as Sadie sat on the plush rug near the wall, carefully arranging her crayons on a sheet of drawing paper.

A quiet knock sounded at the door. Roman stepped inside, carrying a tray with two mugs of hot chocolate and a fresh box of brand-new, unbroken crayons.

Sadie’s eyes lit up instantly. "New crayons!"

Roman knelt beside the little girl, handing her the colorful box. "The best set in the city, little one. For the bravest detective in the house."

Sadie hugged the box tightly to her chest, giving Roman a bright, joyful smile that warmed the cold corners of his heart.

Megan looked up at Roman, her brown eyes filled with endless gratitude. "Thank you, Roman. For everything you've done today. I don't know how we can ever repay you."

Roman sat down on the rug beside Sadie, leaning his broad back against the foot of the bed. "You don't owe me anything, Megan. If it weren't for you and Sadie, Graham would have walked out of this house tonight with twenty million dollars, leaving me to face a federal war."

He looked over at Sadie's drawing paper. The four-year-old was drawing a series of green squares connected by thin black lines, with a strange red circle near the bottom corner.

Roman frowned slightly, staring at the drawing. "Sadie... what is this picture?"

Sadie pointed her small finger at the red circle. "That's the iron door under the grass."

Megan looked at her daughter in confusion. "Honey, what iron door?"

"The one near the flower bushes in the garden," Sadie explained innocently, making a clicking sound with her tongue. "The man with the charcoal suit put a heavy black box inside the red wall, then he turned the brass wheel three times."

Roman’s posture stiffened instantly. He reached out, gently picking up the drawing paper.

The "green squares" were a surprisingly accurate map of the estate's formal gardens. And the "red wall" with the "brass wheel" corresponded perfectly to the old subterranean drainage bunker beneath the eastern terrace—a fortified bunker built during World War II that had been sealed for forty years!

Graham hadn't just hidden a briefcase in the root cellar. He had turned the old WWII bunker into an active storage vault for the Chicago syndicate!
