“A young woman was found murdered in the stream by the softball field.”

“WHAT?”

“Oh, it’s just awful. One of the men playing softball in the league game this morning chased a ball across the path into the water and found a woman’s naked body floating right at the edge.”

I felt sick. My first thought was that it might be someone I knew, an area resident, a friend, or the mother of one of the local children.

I took a deep breath. “Do they know who she is?”

“No, not yet. I heard she was young, maybe in her late teens or twenties. They found her clothes and a Walkman; it seems she was jogging. The police figure she was killed yesterday, probably at dusk, because no one saw her there during the daylight. She doesn’t seem to be a town resident.”

It was a tiny relief to hope she was not someone I knew.

I hung up the phone with a nagging, uneasy feeling that I was somehow more connected to this situation than I should be. For a minute, I placated myself with the idea that it was just the shock of hearing about such a tragedy that made me feel this way. Or maybe it was the fact that this gruesome murder happened right at the ball field where I spent so many happy hours cheering on my son and his baseball team. But it wasn’t that kind of feeling; it was something more eerie. Something was not quite right in the house; a malignant spirit was residing with us now, and it wasn’t the ghost previous residents claimed they had seen on the third-floor landing. I made lunch for my kids and tried to distract myself. The children ate their sandwiches and went out to play. As I put the dishes in the sink, our latest boarder, Walt Williams, came down the stairs from his room into the kitchen. The feeling of anxiety increased.

Walt. It has something to do with Walt.

YEARS LATER, I would dig out the picture of Walt Williams that I had once shown to the police and stare at it. It was the photo I took on a church trip to Six Flags in the suburbs of Maryland just outside of Washington, D.C. The snapshot was dated May 13, 1990. Walt, a twenty-four-year-old African American, was dressed in blue-checked shorts and a white, short-sleeved T-shirt. He was holding the hand of an adoring, giggly prepubescent girl who looked to have a crush on him. He was grinning smugly, looking away from the girl, his chin up in the air. He seemed either arrogant or goofy, depending on how you read the picture, with his boyish face and slight pudginess.

My children were in the picture, too, which made me cringe a bit; my eight-year-old daughter, Jennifer, with her frizzed-out, flyaway hair, courtesy of the gene blend of her blond mother and Jamaican father, and my son, David, age six, who looks rather Hispanic, causing Latinos to state matter-of-factly, “Oh, your husband is from Mexico!”

Walt, our new renter of one week, made the trip to the amusement park rather reluctantly. Although he expressed initial enthusiasm when asked to help chaperone the church teens, that morning when my husband, Tony, and I were ready to depart, he made himself scarce. He had not come down for breakfast nor had I seen him in the hallway.

“Walt?” I called up to his room above the kitchen. “Are you coming?”

“Oh.” I heard a muffled voice through the door. “I was sleeping.”

I was not one to let people who had made a commitment off that easily.

“Well, hurry up. We leave in ten minutes. We’re waiting on you.”

My husband rolled his eyes. He hadn’t been enthusiastic about Walt’s moving in, but it was that or take on a second job to pay the bills. He never liked the idea of anyone living in the house who wasn’t family, but he tolerated our cash-paying international students. Tony was more uncomfortable with the idea of Walt living with us because he thought a working man of his age shouldn’t have to rent a room. He also thought Walt was way too old to be obsessed with Dungeons & Dragons and comic books.

“Well, he is kind of immature,” I offered during our discussion of the new boarder, the present beau of my girlfriend Kim. A few weeks earlier, Walt had applied for a mail room job at her company, and she was the person in human resources who reviewed his application and hired him. Now she was dating him and she asked if we would rent him a room. Walt was looking for a new place to live; he wanted to attend our church and be closer to Kim’s home. Kim was a soft touch, the kind of woman who always tried to help people improve their lives. She told us he didn’t do drugs, didn’t drink alcohol, and didn’t smoke. He was honorably discharged from the air force and had a good work record. We really needed the income from the rental room, as I was a stay-at-home mom, so I agreed to go ahead and interview him. He came across as a pleasant enough fellow, and because my husband and I were in the process of adopting Jeremy, a six-year-old boy from the Delaware foster care system, we also had to have Walt fingerprinted at the local police station. He consented without any hesitation, so we decided to let him move in.

“He’s weird,” Tony said a few days later. “He doesn’t talk with a guy the way guys talk with each other. Actually, I think he avoids me.” I had to agree with Tony that Walt wasn’t a “guy’s guy,” the kind who gets along in groups of males, drinking beer, talking sports, and going golfing or fishing together. He was more of the gamer type. Walt was different from the majority of men his age, but this was one reason I was willing to give him a chance. Rather than being into partying, bars, and one-night stands, Walt had come across as more of a religious sort with strong morals-kind of a Boy Scout. The other reason I may have convinced myself not to be too hard on him was that since fingerprinting became a requirement for any new tenants, our Chinese graduate student applicants found the required trip to the police station too strange and they vanished. We needed money, the room was empty, and beggars can’t be choosers. Besides, I figured many people were a little “different,” but that didn’t make them bad. My friend Kim liked him, and she was levelheaded.

The day at Six Flags was lots of fun for the teens, but when I looked around, we seemed to be one chaperone down. Walt had vanished.

“Have you seen Walt?” I asked Tony.

“Nope.”

We decided to do a quick tour of the park, but we never came across him. None of the other chaperones from the church had seen him either.

Twenty minutes before our planned departure time from the park, Walt suddenly popped up near the exit. Speechless, Tony and I could only stare at the apparition in front of us.

Walt now stood before us dressed in long black pants, a black see-through net shirt, and a black headband. From his left ear dangled a silver skull earring. His hands were encased in fingerless black gloves. He looked completely inappropriate for a teen church outing, creepy even, and the fact that he had disappeared and exchanged one outfit for another was unnerving.

I lacked the courage at that time to question Walt extensively to get to the bottom of his strange behavior. Instead, I only asked, “Where were you all this time?” He just smiled, swung his backpack up over his shoulder, and ignored the question as two giggling church girls ran up to him, grabbing his arms.

Tony and I gave each other a “What is up with this guy?” look. Then we shook our heads, gathered the kids, and headed to the van. Driving out of the parking lot, I pulled down the sun visor on the passenger side to “check my hair” and glanced at Walt’s reflection in the mirror. He sat with his arms crossed, immobile, between Jennifer and David in the backseat, ignoring their discussion of the rides. He had disconnected from the rest of us in the vehicle, his eyes shaded by the dark sunglasses. There was definitely something not quite right about this guy.

Unfortunately, he was now living in my house and he had rights. The law does not permit homeowners to protect their families by evicting renters just because they feel they are a bit peculiar. I couldn’t evict someone without cause and Walt had not broken any house rules. I told myself that I was focusing too much on his quirks instead of his attributes. Walt was friendly, often quite chatty, and he wasn’t a complainer. We actually had some things in common; we both had studied karate, we both wrote fiction, and we both liked going to the movies. We enjoyed a number of pleasant conversations and Walt was never rude toward anyone in the family. He had not acted inappropriately with the children and they were never alone with him anyway, so this was not an issue. I figured I would just keep an eye on him, and if he sent up any real red flags, we would ask him to move on, giving him the proper notice the law required.
