Book Description

Two little boys and a little girl lived with their parents in a big city. One day as they were playing in the yard, the telephone bell rang, and their nursemaid ran to answer it, leaving the children alone in the yard. Mary proposed they go for a walk while no one was watching them, and so they did. But when they wanted to go back, they couldn't remember where their house was and started to cry. Then they spotted a big policeman, who was the first person they met on their adventure.
