Free Killer Smile by Lisa Scottoline

door, covered with black security bars. She followed, and the old woman pressed open the rickety back door, revealing the backyard.
    Mary gasped at the sight. Suspended over the backyard hung a network of weathered ropes, strung together in an elaborate crisscross pattern, making a ceiling of twine diamonds. Laundry hung from the rope canopy on old-fashioned wooden clothes-pins; thin white socks, floppy panties, blouses in different patterns, pajamas, and a series of cotton hand towels. It was the most unusual clothesline Mary had ever seen.
    “Wonderful!” she said. The woman nodded happily and shuffled to the side of the backyard. A rusted metal crank Mary hadn’t seen before had been screwed to the fence, and the woman turned the handle.
    Suddenly, shirts, undies, and black socks moved over their heads, traveling this way and that on the old ropes, following a map only they understood, directed by a series of pulleys. Water sprinkled from the moving canopy, and Mary couldn’t help but applaud. The old woman laughed and sped her cranking, making the laundry go fast, then fly. Droplets sprayed everywhere, and the clothes zipped back and forth in all directions. It wasn’t laundry, it was magic, and the old woman laughed in delight. Mary did, too. And then it hit her.
    The ropes. She watched the whirring laundry and the whizzing ropes, blinking at the droplets that sprinkled her cheeks. The pattern wasn’t diamonds, but squares. It didn’t look like a canopy, it was more like a net. Like a fisherman’s net. Remade, restrung, and redesigned on pulleys to make a wonderful clothesline. Was it possible? From so long ago? It looked old enough, considering the thinness of the weathered ropes and the rust caking the metal crank.
    Suddenly Mary wasn’t laughing. How many people had owned the house since Amadeo? It couldn’t be that many. People down here didn’t get off the couch, much less move from their family home. Mary’s parents were typical of South Philly; the house she had grown up in on Mercer was the very house in which her mother had grown up. Even if the house had changed hands a bunch of times, who would cut down a contraption like this? It was useful, unique, and fun.
Amadeo made this for Theresa.
Mary knew it; she felt it
inside
. She was about to ask the old woman when a shout came from the door.
    The cranking stopped abruptly, the laundry came to a halt, and Mary turned. A young man of about twenty-five, his dark hair disheveled from sleep, stood in the doorway shouting in Korean at the woman, who cowered in the corner. He was lean and bare-chested in low-slung gym shorts, but he was oblivious to his own nakedness. His angry glare turned on Mary.
    “What are you doing with my mother?” he demanded. “You woke me up!”
    “I’m so sorry, really sorry. Really sorry.” Mary was on an apology roll. Hey, maybe she did have a forte. “I just wanted to see the house and ask a few questions about a former owner, named —”
    “Oh, you’re the one!” The young man threw up his hands. “They were asking have you been here! You know that jerk with the zits?”
    Mary felt a chill. Jerk with the zits. The Escalade driver. “No, not at all. My name is —”
    “I don’t care, I need my sleep, I work all night. Get out of here!” The young man faced his mother and began yelling again, but Mary couldn’t shake that chill. What was going on? And what about the clothesline? The laundry still dripped from its merry trip.
    “I’m sorry, I’ll leave right now,” Mary said again. “I just need to know if you made this clothesline.”
    “No!”
    “How long have you lived here?”
    “Seventeen years, eighteen, none of your business. Listen, I worked all night. I have to go back to bed. Leave now. Go!”
    “Was the clothesline here when you got here?”
    “Leave, I said! You want me to call the cops?” the man shouted, then turned on his mother.
    “Wait, stop!” Mary interrupted, raising a palm. She
