Margaret Hale had never expected much from the condemned house everyone in Bellweather called Wren House. After her husband Thomas died, she bought the abandoned property at auction for one dollar, mostly because she couldn’t stand watching another piece of the town’s history disappear. The house had belonged to Silas Wren, a mysterious watchmaker who had vanished nearly a century earlier. The roof leaked, the windows were boarded, and orange condemnation tape fluttered around the porch. Everyone told Margaret she had made a foolish mistake. Then a developer named Dean Mercer began showing unusual interest in the property. He offered her money to walk away, but she refused. A week later, someone slipped a note under her door warning her to sell before she discovered what the house was hiding.

Margaret almost dismissed it as a prank. Instead, she remembered something Thomas had once told her: old houses rarely hide what people expect them to hide. She returned to Wren House with a flashlight and began searching room by room. Behind a damaged fireplace, she noticed bricks that didn’t quite match the surrounding stone. Her hands trembled as she loosened the first one. Behind it was a narrow cavity, and inside that cavity sat a dusty leather satchel. Margaret opened it, expecting perhaps old papers or worthless scraps. What she found inside made her forget all about Dean Mercer.
