In Garman's Street, there live quite ordinary people. Only one old man, the "stamp man," is a bit eerie. The former postman buries himself in the house with the overgrown garden. People tell stories about his cellar, where old letters are stacked up to the ceiling. However, Garman is only interested in the garden, with plants like the dog's tooth violet that he would love to have for his herbarium. It takes him a long time to muster the courage to enter the garden. But there, he experiences a surprise: the old man is a bit strange, but he is not mean. A whimsical picture book about how prejudices can dissolve into thin air.
