Reading book 2 again, I got to wonder about something.

Grimmauld Place 12 as well as Lily/James' hideout at Godrics Hollow 
couldn't be seen or found by anyone who wasn't told the location by the 
Secret Keeper, as we all know.

Now, an example.
Say Harry tells someone - Justin; just to give a name - where to find 
Grimmauld Place.
That wouldn't work for Justin, since Harry is not the Secret Keeper of 
Grimmauld Place.
Now - what if Justin polyjuices himself into Harry and *then* tries to 
locate Grimmauld Place - would that work? For Justin to locate the 
place?

Just wondered.....
