Part 2: My family kicked my 7-year-old and me out during Christmas dinner. "You should leave and never return," my sister said.

I set my coffee mug down on the wooden side table and stepped off the swing, wiping my hands on my jeans.

“Thanks, Tom,” I smiled, signing the electronic pad he held out.

The envelope was heavy, made of thick, cream-colored bond paper with no return address—only a crisp, official postmark from Zurich, Switzerland.

My heart gave an uneasy thud. Mark had done international audit work six years ago, but all his foreign clients had been settled and archived long before his illness.

I tore open the top edge. Inside were two items: a high-security safety deposit key with the number *804* etched into the brass, and a single handwritten letter on hotel stationery.

The handwriting wasn't Mark's.

It was sharp, elegant, and entirely unfamiliar:

*“Dear Clara,*

*If you are reading this, it means Mark’s domestic estate has finally cleared probate and your sister’s interference has been handled. Mark anticipated that his family would attempt to ruin you. What he did not anticipate was that the men he investigated during his final corporate audit in Chicago were watching his house.*

*The break-in at your home two weeks after his funeral was not Trent looking for insurance papers.*

*Trent was an amateur looking for pocket money. The people who were really in your home that night took something else entirely—something Mark buried in the foundations of the Oakridge property before you signed the deed.*

*The house you just sold to that young couple last week?*

*Get them out. Now.*

*They are coming to dig it up.”*

A cold gust of wind swept across the sunny porch, making the wind chimes ring with a frantic, hollow chime. Down in the yard, the puppy stopped playing, ears pinned back, growling at the empty treeline at the edge of the property.

My phone rang. The screen displayed an unknown international number.
