This One's a Little Different
I never thought much about square footage until that year. Uncle Marcus left me his workshop in his will—just the building, not the land. "Take whatever you want from inside," the lawyer said. I expected tools, maybe some furniture. Instead, I found notebooks filled with radio frequencies and star charts, arrows connecting moon phases to coordinates. The workshop felt cramped despite being empty. I paced it off: thirty feet one way, thirty the other. Nine hundred square feet should feel spacious, but the walls seemed to press inward. Then I found his shortwave radio, still tuned to 144.39 MHz. Static filled the space until midnight, when a woman's voice cut through: "Huntress to base. Perimeter secure. Next sweep at oh-three-hundred." I thought it was military chatter until I cross-referenced Uncle Marcus's notes. The frequency, the timing, the call sign—everything matched his calculations about "watchers" and "the hunt." His final entry read: "They know I'm listening. Moving to smaller space. Harder to track in 30x30." The voice crackled again: "Anomaly detected. Triangulating source." I switched off the radio, but kept the notebooks. Some signals, I realized, aren't meant to be interpreted.
