I have started and stopped writing this post five times tonight. My hands will not stop shaking. Putting this into words makes it real, and I have spent the last two weeks trying to keep my voice steady so I could actually help my son instead of falling apart right in front of him.

Caleb is five years old. He has always been a happy, bright kid. Or at least he was, until a couple of months ago.

Lately, he had gotten so clingy at school drop-off that I had to peel his little fingers off my sweater. He started wetting the bed again after being dry for over a year. He went quiet in a way that just wasn’t like him. I honestly thought it was just the divorce. His father, Brandon, and I split up last spring, and the transition hasn’t been easy on anyone. Caleb does every other weekend at Brandon’s new place across town. I kept telling myself it was just a phase, a natural reaction to the change in his routine. I suppose I wanted to believe that because the alternative was too terrifying to even look at.

Then, the prayers changed.

We have a routine every single night. We do the same prayer my own grandmother taught me when I was a girl. Two weeks ago, Caleb started adding his own little line at the very end. He said it fast, mumbled under his breath, like he was hoping I wouldn’t actually catch it. I let it go the first few times. I figured he was just tired or maybe dreaming out loud. But last night, I was standing in the hallway with a heavy basket of laundry, and I stopped cold right outside his door.

“And please don’t let Mr. Kellan come in when the light’s off.”

I felt the blood drain right out of my face. I set the basket down on the floor.

Very slowly. I didn’t want to make a sound that would alert him that I had heard. I walked into the room and sat on the edge of his bed. I kept my voice light and airy, the way you have to do when everything inside you has turned to ice and you cannot let the child see the panic.

“Caleb, honey, who is Mr. Kellan?” I asked.

His whole face changed. He pulled the blanket up to his chin and shook his head vigorously. He told me Mr. Kellan said it was a secret and that secrets keep you safe. My chest felt like it was being crushed by a weight. I asked him if Mr. Kellan was at Daddy’s house. He nodded, just one small, sharp nod, and then he pressed his lips together and wouldn’t speak another word.

I went to his desk and got his drawing pad. I told him he didn’t have to say anything out loud, that he could just draw it or write it, and that no one would ever be mad at him for telling the truth. He took the crayon, his hand shaking, and he wrote in those uneven, five-year-old letters: KELLAN. Below it, he drew a tall, jagged stick figure standing in a doorway. He drew a small figure in a bed, and he had colored the entire room solid black, except for one thin, haunting strip of yellow light leaking in from under the door.

My mouth went completely dry. I asked him, as gently as I possibly could, one more thing. “Is Mr. Kellan a grown-up who lives at Daddy’s?”

Caleb wrote one more word on the page.

BASEMENT.

Brandon moved into that rental property back in March. It is a two-story house with a finished basement. He had mentioned a roommate to me a while back, just some guy from his office who needed a place to stay while he got back on his feet. I had never met the man. I had never even asked his name. Why would I have? I trusted the court-ordered schedule. I trusted that my son was safe on those weekends with his father. I feel sick just thinking about how naive I was.
