My father-in-law and I were alone at home. My husband had gone to work, and I was doing my usual chores. Suddenly, I felt a heavy hand on my shoulder.
“Where is your husband?” — a hoarse voice sounded behind me.
I turned around. My father-in-law was standing in front of me. His face was pale, and his hands were trembling.
“He’s at work,” I replied in confusion. “What happened?”
“Go to the bathroom quickly. I found something there… I think it belongs to your husband.”
My heart tightened.
“He… is cheating on me?” — I whispered.
“No.” But it’s better if you see for yourself.
I went into the bathroom. And then I froze. The wall near the sink was broken. Pieces of tile and cement were scattered on the floor, and in the dust — a transparent plastic bag.
My father-in-law silently pointed at it. I bent down, carefully picked it up, and opened it.
And inside was… 
Continuation — in the first comment 
I was standing in the bathroom and trembling all over from fear. My heart was beating fast. I couldn’t speak, couldn’t move. I was frozen.
“Oh, my God…” I finally whispered. “Wh-what is this?”
My father-in-law was silent, his eyes full of anxiety.
“Open it. It’s not an ordinary bag.”
I looked at him.
“Tell me, what does my husband have to do with this? What is going on here?”
He took a deep breath and finally, with a trembling voice, began to speak:
“It’s inside the bag. It’s documents. I found out that he and his friends are hiding something. And later, one evening, I followed him… my own son… I saw something. He went down into the basement, took out large envelopes, flash drives, notebooks. I didn’t dare to ask.”
I looked at him:
“What documents?”
My father-in-law nervously ran a hand through his hair.
“He’s been acting strange lately. Very closed off. Sometimes he disappears for a few hours. And if you try to ask him where he’s been, he avoids answering.”
I swallowed hard.
“But I’m sure whatever it is, it’s here, in this bag,” I said quietly.
My father-in-law’s trembling voice added:
“Once he told me himself. That evening. He was drunk and said: ‘Dad, there are things a man shouldn’t know.’ Then he tore up some papers, locked himself in his office. When I knocked, he shouted at me. Since then, I can’t understand him anymore.”
Silence fell between us. I felt like I was standing in the middle of a terrible secret.
“Wait, what’s inside then,” — I asked, trembling with fear.
My father-in-law’s lips moved:
“We have a choice now. Either we open it and find out everything right now… or we pretend we didn’t see anything. But remember, if your husband is really involved in something, that truth could destroy us.”
