“如果麦格是你的头号嫌疑犯,”赫敏慢条斯理地说,“这不就意味着她不是你最后的怀疑对象,因此她不是犯人?” (注:"If McGonagall is your prime suspect," Hermione said slowly, "then doesn't that mean she isn't the last one you suspect so therefore she isn't the culprit'这逻辑。。。)
“是的!但麦格很聪明。她知道自己是你最不会想到的人,因此你会最先怀疑她。然后,为了不成为最不可能的嫌疑犯,她就不会和她的邪恶计划扯上关系。” (She knows she'll be the last one you suspect, so therefore you'll suspect her first. Then, by not being the last one to be suspected, she will get away with her fiendish plans.)
