I married a widower with a young son — one day, the boy told me that his real mother still lives in our house.

‘My real mum still lives here,’ my stepson whispered one evening. I laughed it off until I started noticing strange things around our house.

When I married Ben, I thought I understood what it meant to enter the life of a widower. He was so devoted to his late wife, Irene, and was raising their seven-year-old son, Lucas, on his own.

I respected his deep love for her, knowing that it was tied to the memory of his first love and Lucas’s mother. I wasn’t here to replace her, but to start a new chapter for all of us.

The first few months of married life were everything I had hoped for. Lucas accepted me warmly, without the hesitation I had feared. I played games with him for hours, read his favourite bedtime stories and helped him with his schoolwork.

I even learned to cook his favourite macaroni and cheese just the way he likes it — with cheese and breadcrumbs on top.

One day, out of the blue, Lucas started calling me ‘Mummy,’ and every time he did, Ben and I would exchange proud smiles. It seemed like everything had fallen into place.

One evening, after a cosy night, I was putting Lucas to bed. Suddenly, he looked up at me, his eyes wide and serious. ‘You know, my real mum still lives here,’ he whispered.

I giggled softly, running my fingers through his hair. ‘Oh, sweetie, your mummy will always be with you, in your heart.’

But Lucas shook his head, squeezing my hand so hard it made my heart ache. ‘No, she’s here. In the house. I see her sometimes.’

A chill ran down my neck. I forced myself to smile and chalked it up to a child’s imagination running wild. ‘It’s just a dream, sweetie. Go to sleep.’

Lucas calmed down, but I felt uneasy. I pushed those thoughts away, telling myself that he was just getting used to his new family, to his new normal. But as the days went by, little things around the house began to bother me.

First, I would put away Lucas’s toys, only to find them back in exactly the same place where I had taken them. Not once or twice, but again and again.

And the kitchen cabinets — I rearranged them the way I liked, but the next morning everything was back in its place, as if someone was trying to undo my changes to the house. It was unnerving, but I told myself it was just my mind playing tricks on me.

One evening, I noticed something I couldn’t explain. I had moved a photo of Irene from the living room to a more inconspicuous shelf in the hallway. But when I went downstairs the next day, it was back in its old place, perfectly dusted, as if someone had just cleaned it.

I took a deep breath and decided to discuss it with Ben. ‘Do you move things around the house?’ I asked one evening, trying to sound casual as we finished dinner.

Ben looked up and smiled as if I had told a silly joke. ‘No, Brenda, why would that be? I think you’re just making it all up.’

He laughed, but there was something in his eyes — a hint of discomfort or perhaps reluctance. I couldn’t quite put my finger on it, but I felt an invisible wall between us.

A few evenings later, Lucas and I were solving a puzzle on the living room floor. He was concentrating on arranging the pieces, sticking out his little tongue intently, when he suddenly looked up at me, his eyes wide and sincere.

‘Mummy says you shouldn’t touch her things.’

My heart skipped a beat. ‘What do you mean, sweetie?’ I asked, trying to keep my voice steady and looking towards the hallway.

Lucas leaned towards her, lowering his voice. ‘My real mum. She doesn’t like it when you move her things,’ he whispered, looking over his shoulder as if expecting someone to be watching us.

I froze, trying to make sense of his words.

He looked at me so seriously, as if he were sharing a secret he shouldn’t have revealed. I forced myself to smile, nodded, and squeezed his hand lightly. ‘It’s okay, Lucas. You don’t have to worry. Let’s finish our puzzle, okay?’

But that night, as Ben and I lay in bed, my thoughts raced. I tried to convince myself that it was just an overactive child’s imagination. But every time I closed my eyes, I heard Lucas’s words and saw him nervously glancing towards the hallway.

When Ben finally fell asleep, I quietly got up and headed for the attic. I knew Ben kept Irene’s old things in a box there. Perhaps if I could see them and learn more about her, it would help me understand why Lucas was behaving the way he was.

I climbed the creaky stairs, shining my torch into the darkness until I found the box tucked away in the corner, dusty but well cared for.

The lid was heavier than I expected, as if it had absorbed years of memories. I opened it and found old photographs, letters she had written to Ben, and an engagement ring, carefully wrapped in cloth. It was all so personal, and I felt a strange sense of guilt as I rummaged through it.
