The woman looked like Karly, but I couldn’t be sure. Maybe I just wanted it to be her.

Even so, I followed. I took the alley to the back of the building, where the dormitories and fraternities came together in a kind of quad. It was almost impossible to see in the darkness back here. Trees crowded the open lawns and blocked my view. Ivy-covered walls butted up to the cobblestoned sidewalks. I didn’t see Karly—if it really was Karly—but she couldn’t have gone far. I heard the tap of her heels on stone, but the noise bounced between the walls and made it hard to tell where she was.

I crossed beside a building with Greek letters engraved over its doorway. Bike racks were crowded near the rear door, and I smelled weed through one of the windows. I stopped by the dense, overgrown hedges and listened again, hearing no footsteps this time. Then, on the far side of the lawn, I spotted a flash of her blond hair as she passed under the glow of a lamppost. She disappeared into a narrow corridor between two buildings. I changed direction to go after her, navigating between the trees. The branches dangled low to the ground, scraping my face as I hurried through the damp grass.

When I was halfway across the lawn, I stopped.

A stab of horror ran through my body. Ahead of me, a silhouette detached itself from the thick trunk of an elm tree. It was a man. He stood on the fringe of the grass, framed in darkness by the lamppost. I recognized the outline of his body, because I’d seen it in photographs throughout my life. That was how I looked, with my lean, small frame, with my shock of wavy hair. It was me. It was him. He headed after the blond woman with a determined stride, and as he crossed under the light of the lamppost, I saw the dirty leather of his coat. My father’s coat. I also saw a glinting reflection of something metal in his hand.

A knife.

He was carrying a knife.

I tried to run, but the slick mud under my feet slowed me down. When I got to the walkway between the buildings, the corridor was already empty. I sprinted to the far side and found myself in a wooded area where four sidewalks met in a cross, with more ivy-covered walls on every side. My doppelgänger was gone. So was Karly.

Was it Karly?

Was I going to lose her again?
