Bless them, they'll go to any lengths to ignore magic, even if it's staring them in the face…

（まったく彼らときたら、たとえ目の前で魔法が起ころうとも、それを認めないためなら、どんなことだって考えつくんだから…。）
　『Harry Potter and the Chamber of Secrets』（ハリーポッターと秘密の部屋）より。魔法省に勤めるウィーズリーおじさんが、今日の仕事のことを子供達に話すシーン。鍵がどんどん縮まっていく魔法をかけられても、魔法を信じないマグルたちは、自分が鍵をなくしてしまったんだと言い張る、という話で。

• "go to any length"、"go to/great/some/extreme lengths" は、「〜するためならどんなことでもする、努力を惜しまない（to do whatever is necessary／to try very hard or to do whatever is necessary to achieve something that is important to you／to make a great or extreme effort to do something／to put a lot of effort into doing something, especially when this seems extreme）」という意味だけれど、ここでは「鍵がなくなるなんて魔法があるわけがない、自分がなくしたんだ」というマグルの考えを述べた後のセリフなので、「どんなことだって考える」というふうにしてみた。
