《神探夏洛克》精讲 334叫不来电梯（在线收听）

Do we really need so much colour?

非要这么生动吗?

It passes the time.

打发时间嘛

But if I do this...

但如果我这样...

If you press a keycard against your mobile phone for long enough,

把门禁卡在手机上多按一会

it corrupts the magnetic strip. The card stops working.

卡就会消磁 不能再用了

It's a common problem. Never put your keycard with your phone.

磁卡的通病 别把卡和手机放在一起

What happens if I use the card now?

如果我现在去刷这张卡又会怎样?

It still doesn't work.

还是叫不来电梯

But it doesn't read as the wrong card now.

但显示的就不是错误

It registers as corrupted.

而是卡片故障

But if it's corrupted, how do they know it's not Magnussen?

如果是故障 怎么知道那不是马格努森呢?

Would they risk dragging him off?

他们会冒险惊扰老板吗?

Probably not.

应该不会

So, what do they do? What do they have to do?

那怎么办? 唯一办法?

Check if it's him or not.

先确认来者身份

There's a camera at eye height to the right of the door.

门右侧眼高处有摄像头

A live picture of the card user

显示刷卡者的即时影像

is relayed directly to Magnussen's personal staff in his office,

会直接发送给玛格努森办公室里的员工

the only people trusted to make a positive ID.

能辨识来者身份的可靠人士

At this hour, almost certainly his PA.

在这个时间 基本肯定就是他的私人助理

So, how does that help us?

那对我们又有什么用?

Human error.

人性的失误

I've been shopping.

我买了东西
