Within five minutes, loud sirens echoed down the quiet suburban street.
Three police cruisers pulled up onto the circular driveway outside.
Armed officers rushed through the open front door into the grand hall.
Mark pointed up toward the top of the curved marble staircase.
"The suspect is upstairs in the main office," Mark told the lead officer.
The officers drew their sidearms and moved carefully up the steps.
Arthur tried to escape through the back balcony door, but officers cornered him.
They placed metal handcuffs on Arthur's wrists and led him down the stairs.
Arthur kept his head down, refusing to look at Mark or Sarah.
"You're ruined, Mark! The company will collapse after this!" Arthur spat angrily.
"The company will survive, Arthur. You are the only one who is ruined," Mark replied.
Paramedics arrived shortly after to examine Sarah and small Lily.
They cleaned the light scratches on Sarah's face and gave her a warm blanket.
Mark sat beside his wife and daughter on the plush sofa in the living room.
He held Sarah's hand tightly, never wanting to let go again.
The police took photos of the open trapdoor and the dark cellar below.
That trapdoor had been built decades ago by the mansion's previous owners.
Arthur had found it on old architectural blueprints and used it for his crime.
Now, the dark secret was exposed, and the danger had passed completely.
Mark looked around his bright, sunny home, feeling a profound sense of relief.
His family was safe, his business was secure, and justice had been served.
