How can I take Sarah's personal effects?


Hint 1 of 8:
You will need permission from someone at Scotland Yard.

Hint 2 of 8:
Gregson can't give you permission, but he'll tell you who can.

Hint 3 of 8:
If you need help getting into the Yard, see a later question.

Hint 4 of 8:
Now all you need to do is contact Lestrade.  A bit of inside help is needed.
