They were going even deeper now and gathering speed. The air became colder and colder as they hurtled round tight corners. They went rattling over an underground ravine, and Harry leaned over the side to try to see what was down at the dark bottom, but Hagrid groaned and pulled him back by the scruff of his neck.

　　Vault seven hundred and thirteen had no keyhole.

　　"Stand back," said Griphook importantly. He stroked the door gently with one of his long fingers and it simply melted away.

　　"If anyone but a Gringotts goblin tried that, they'd be sucked through the door and trapped in there," said Griphook.

　　"How often do you check to see if anyone's inside?" Harry asked.

　　"About once every ten years," said Griphook with a rather nasty grin.

　　Something really extraordinary had to be inside this top security vault, Harry was sure, and he leaned forward eagerly, expecting to see fabulous jewels at the very least -- but at first he thought it was empty. Then he noticed a grubby little package wrapped up in brown paper lying on the floor. Hagrid picked it up and tucked it deep inside his coat. Harry longed to know what it was, but knew better than to ask.

　　"Come on, back in this infernal cart, and don't talk to me on the way back, it's best if I keep me mouth shut," said Hagrid.

　他们继续乘小车往下走，而且速度更快了，当他们呼啸而过一个接一个的拐角时，空气变得越来越冷。他们的小车嘎嘎地越过一座地下山谷，哈利靠向车的一边想看看漆黑的谷底到底有什么东西，但是哈格力拉着他的脖子把他拽了回来。

　　713号金库找不到锁眼。

　　"往后站，"格里霍克很严肃地说，他用一根细长的手指轻轻地敲了一下门就打开了。

　　"除了格里霍克的恶魔之外的任何人如果试着这样做了，他就会被门击中，跌入陷阱里。"格里霍克说。

　　"你们多长时间检查一次是否有人在里面。"哈利问道。

　　"大概十年一次吧。"格里霍克说着，露出一副很狡诈的笑容。

　　哈利确信，一定有什么与众不同的东西隐藏在这间高级密室里，他急切地把身子往前探，盼望着最起码见到一些极好的宝石——虽然在开始他以为这间房是空的。

　　但后来他注意到一个用棕色皮纸包着的肮脏的小包裹躺在地板上，哈格力把它捡了起来收到衣服里去，哈利很想知道包裹里是什么东西，但他也知道还是不问为好。

　　"来吧，回到这可怕的小车上来，在回去的路上不要跟我说话，能把嘴闭上，我会感到好点的。"哈格力说。
