The narrator of Timm's story is a writer who simply can't get started on his next book. So he accepts a commission to write an article about potatoes. He has some interest in the subject because of an uncle who could, remarkably, from taste alone, differentiate one species of potato from another. Since it turns out that one of the authorities on the subject worked in East Berlin, our hero takes off to do some research. The Washington Post has lauded Uwe Timm's ability to make a place -- in this case the new Berlin --"more real for you than the place you grew up. Timm is essentially an anthropologist of this primitive computer age, an archaeologist of newly constructed places".

Rushing between the East and West sectors of the now-united city, the narrator becomes involved in a series of madcap adventures: odd, sometimes threatening encounters with all sorts of people, and strange entanglements. Being the master storyteller that he is, Uwe Timm spins a fascinating tale here, one filled with surprise, magic, comedy, and hope.
