I figured an antique like that had to be worth a few hundred dollars to a collector, maybe enough to cover my groceries and electric bill for the month. I took out my phone, snapped a few photos of the woodwork, and prepared to list it online.

Before I could even hit publish on the advertisement, my phone buzzed in my hand. It was a text message from Eleanor. I stared at the screen, my stomach tying itself into knots. I hadn’t spoken to her since the day the movers left. I fully expected it to be a message asking for the piano back, or maybe some hollow pleasantry to ease her own conscience.

Instead, it was a chilling, cryptic directive. “Don’t sell it — open the desk cover. There is a small latch underneath the center hinge. Press it.” My blood ran cold. The message was so specific, so utterly out of character for the usually proper and reserved Eleanor.

I put my phone down and slowly walked over to the piano. The apartment was dead silent as I ran my fingers along the polished wood of the fallboard—the cover that protects the keys. I crouched down, feeling along the underside of the center hinge just like she instructed.

Sure enough, my finger brushed against a small, cold piece of metal. It didn’t look like a latch at all, just a decorative screw, but when I pressed hard against it, I heard a sharp click. The back panel behind the music rack suddenly sprang loose.

I carefully pulled it forward, revealing a narrow, hidden compartment built directly into the backing of the instrument. It was dusty and smelled faintly of old paper and cedar. Reaching inside, my hand brushed against something thick and heavy. I pulled out a large manila envelope.

It was sealed tight with packing tape. My hands were shaking as I grabbed a pair of scissors from my kitchen counter and sliced it open. When I dumped the contents onto my cheap dining table and finally looked at what was tucked away in that secret space, my jaw literally hit the floor.

His own mother had been keeping a massive, dark secret from him. Spilled across my table were dozens of documents, bank statements, and legal ledgers. On top of it all was a handwritten letter from Eleanor. I opened the letter first, my eyes scanning her neat, cursive handwriting.

“My dearest daughter,” the letter began. “I have watched my son destroy you, and it has broken my heart. I raised him to be a good man, but greed has poisoned him. What he didn’t know, and what his lawyers failed to uncover, is that for the past five years, he has been siphoning money not just from your joint accounts, but from the estate my late husband left to me.

He thought I was too old and naive to notice.
