What does the author notice one Sunday afternoon? What is his mother’s reaction? What does she do?

One Sunday afternoon, the narrator was sitting at the dining table doing his homework. It was very cold outside so his mother was tending the fire to keep them warm and nice. Suddenly the author noticed smoke coming out from the roof. In no time, the room was full of smoke and they could not even see. They somehow managed their way outside the house and by then the flames had spread throughout the house. The narrator ran to the neighbour’s place to call the fire brigade. The narrator's mother ran back into the house and returned with a small box full of important papers. She dropped the box and ran again to collect the pictures and letters of her husband who wasn’t alive anymore.
