……
1971年，夏天。
一大早，斯内普被一阵清脆的“笃笃”声吵醒。他略微烦躁地坐起来，看向制造声音的罪魁祸首——一只灰林呺。那只猫头鹰看到斯内普醒了，更加用力地用喙敲打着窗玻璃。斯内普打开窗户，将猫头鹰爪子上的信解下来。
随便给猫头鹰喂了点东西，斯内普看了看羊皮纸信封。信封右下写着地址：伦敦蜘蛛尾巷31号，一楼客房，西弗勒斯·斯内普先生。没错，是蜘蛛尾巷31号，而不是蜘蛛尾巷19号。斯内普离开了那个混乱的家，住到了克瑞娅家的客房。
霍格沃茨的信。斯内普打开信，浏览着里面的内容。

看了一部分，斯内普没了耐心。他将信纸折起来放好，又拿了张纸写明回信。

另一边，对角巷。
一家有些凌乱的草药店里，克瑞娅慢条斯理地擦拭着木架。“来的这么早啊小克瑞——”草药店的老板玛丽莎夫人趿拉着拖鞋从二楼下来，手里还“拎”着一只小猫头鹰：“这只霍格沃茨的小猫头鹰似乎飞昏了头，扑到我的卧室里来了。”
“霍格沃茨？”克瑞娅将那只无助的扑腾着的猫头鹰从玛丽莎手里解救出来：“找我？”
“不然呢？”玛丽莎奇怪的看了她一眼：“算算时间……霍格沃茨的猫头鹰该来送入学通知了啊？”
“可我不是巫师。”克瑞娅平静地放下抹布，把小猫头鹰腿上的信解下来。玛丽莎顺手给它塞了块面包，它埋头吃起来。
“确实……从来没见你魔力暴动过小克瑞。”玛丽莎挠挠头：“可是准入之书是不会出错的……至少没人见过它出错。”
“那你现在见到了。”克瑞娅拆了信，匆匆扫了一眼：“或许我应该写一封回信说明一下，我并不能去上学。”
“好吧。”玛丽莎无所谓地耸了耸肩：“随便你了小克瑞，我拿张信纸给你。”

玛丽莎风风火火上楼去了，把木质楼梯踩得“咚咚”作响。克
