A Garden Discovery

Strolling past the porch along the crushed gravel path, my gaze caught a flash of bright brass nestled inside the slatted side of an old wooden wheelbarrow. Why would anyone leave a heavy, weathered brass padlock resting atop a dry burlap sack unless it guarded a puzzle? I hopped up onto the lower wooden strut and leaned over the rough timber rim to examine it. Its weathered dial had three rotating letter rings! With a poised nudge of my thumb, I aligned the letters until a satisfying click echoed across the garden bed, releasing the shackle with a gentle pop. What a marvelous midday mystery solved, wouldn't you say?
