Book excerpt: An elderly caretaker at a large outdoor exhibition, called Art in Nature, finds that a couple have lingered on to bicker about the value of a picture; he has a surprising suggestion that will resolve both their row and his own ambivalence about the art market. A draughtsman's obsession with drawing locomotives provides a dark twist to a love story. A cartoonist takes over the work of a colleague who has suffered a nervous breakdown only to discover that his own sanity is in danger. In these witty, sharp, often disquieting stories, Tove Jansson reveals the fault-lines in our relationship with art, both as artists and as consumers. Obsession, ambition, and the discouragement of critics are all brought into focus in these wise and cautionary tales.
