What's hidden behind... It's a mystery and an invitation to travel. Opening the closed and seeing what's hidden there is an irresistible temptation for those who want to explore the world. Sometimes it's not easy, and it doesn't always end well, but you should never give up.

The book tells the story of a small child living an ordinary day—the world is full of secrets and mysteries for a person who is just beginning to explore it. After all, it's so interesting to find out where a new smell will lead or what's behind the closet door! Tireless curiosity is a natural stage that every person goes through, and it's very important that this childish inquisitiveness lasts a lifetime.
