The only light came through the open door, and the only sound from the buzzing of an electric sweeper in the hand of a tall, tired man who seemed unwilling to lift his eyes from its repetitive path.She tried repeating “Excuse me?” at varying volumes, but if he did hear her above the machine’s din, he gave no indication. Waving her arm to catch his eye proved equally fruitless, and it wasn’t until she moved directly into the sweeper’s path that he even looked up, and then not until the machine had tapped the toe of her sturdy brown shoe.“Whaddya want?” Not only did he not turn off the machine; he continued to maneuver it in a narrow arc around her feet.“I’m looking for Mr. Lundi. Roland Lundi?” The fact that she had to shout made her sound bolder than she felt, and for that she was grateful.“Back office.” He ran the sweeper to the left, indicating the direction she should take, and she obeyed.The building only got darker the deeper she walked. Muffled voices guided her through the gray, and a strip of light beckoned.
