U.S. Army signal intelligence engineers spent several days running hundreds of yards of wires through the house, under floorboards, behind walls, inside furniture cushions and lighting fixtures. In a final touch, they wired the garden for sound. The engineers burrowed through the backyard garden and attached tiny microphones to a single tree above the sitting area. All wires connected back to a recording machine capable of laying audio tracks down onto gramophone records. This was high technology in the summer of 1945.
