In his bestselling debut picture book, the multiple award-winning Jon Klassen, illustrator of This Is Not My Hat and Sam and Dave Dig a Hole, tells the story of a bear who's hat has gone. And he wants it back. Patiently and politely, he asks the animals he comes across, one by one, whether they have seen it. Each animal says no (some more elaborately than others). But just as it he begins to lose hope, lying flat on his back in despair, a deer comes by and asks a rather obvious question that suddenly sparks the bear's memory and renews his search with a vengeance...Told completely in dialogue, this quirky, hilarious, read-aloud tale plays out in sly illustrations brimming with visual humour and winks at the reader who will be thrilled to be in on the joke.

大熊的帽子不见了！他想把它找回。耐心且礼貌的询问他遇到的动物朋友狐狸、青蛙、兔子、乌龟、蛇，是否有看到他的帽子，但每个动物都说没有。当大熊陷入万分沮丧时，遇见了鹿，鹿提出了一个简单的问题，引发了大熊的记忆，他能找到他的帽子吗？

鲜明的中国水墨画插图，在绘者洒脱的笔触下，将动物们呆滞的表情，忧郁、紧张及愤怒等情绪，透过画面充分表露。以大量的留白来突显文字与构图，左右页搭配内文的比较性，增强视觉效果。文字是黑色，棕色，绿色和红色，反映谁在说话从而开始读者遵循的叙事。在插图微妙的渲染，与简短的内文成为一个完美搭配，令人赞赏，更表现出文字与图画的意函及趣味。
