Late on Christmas Eve, after the town has gone to sleep, a boy boards a mysterious train that waits for him: the Polar Express bound for the North Pole. When he arrives there, Santa offers him any gift he desires. The boy modestly asks for one bell from the reindeer’s harness. It turns out to be a very special gift, for only believers in Santa can hear it ring.
原著は「The Polar Express」Chris Van Allsburg。日本語版の訳は村上春樹です。
これも原著で読めるのでそちらを読みましょう。
村上訳の「妙」も面白いですけどね。
