Did Bill Weasley create a plot hole?

As I understand it, the fidelius charm's protection applies to the location of a place, not the people residing in a place. By saying that the Weasleys are at "Auntie Muriel's", Bill is not disclosing ...

What happens when Veritaserum and a Fidelius Charm meet?

The first thing I'd say is that Veritaserum is only one tool. It may be magic, but it is not invincible, it is not infallible. Rowling has gone on record saying: [Veritaserum works best on] the ...

While not stating it straight out, it appears that you can remember where-about the house was, but you'll not be able to locate it anymore. Professor Flitwick cleared his throat. ‘An ...

Does the Fidelius Charm keep out owls, cats, elves?

Owls at least can penetrate Fidelius charms. Harry sends Hedwig to Ron and Hermione who were both staying at Grimmauld Place, before Harry himself learns of their location. After learning the "secret" ...

Why did Harry, Ron, and Hermione think it safe to hide in Grimmauld Place?

The problem is that JKR changed her mind about how the Fidellius charm worked. Originally, the charm was incredibly strong - only one person could ever reveal the secret. If that person died, no ...

What was the Fidelius secret that Peter Pettigrew concealed?

It did NOT protect the Potters themselves. Here is what Lilly wrote in a letter to Sirius (Harry Potter and the Deathly Hallows, Chapter 10): We had a very quiet birthday tea, just us and old ...

Can a Secret Keeper break their Fidelius Charm?

No. If it were possible for a Secret Keeper to break the charm, the Death Eaters would have expected Snape to do so with the charm on 12 Grimmauld Place. The tongue-tie curse prevented him from ...

It's doubtful. I think that, on the whole, it wouldn't be possible to stack multiple Fidelius Charms onto a single location (although it doesn't happen in canon so we don't know for sure). Firstly, ...

Given that it was under the Fidelius Charm, why did Grimmauld Place require any additional magical protection?

There was need of extra security. In Deathly Hallows a Death Eater latched onto Ronald while they were escaping the Ministry, and got sucked back to Grimmauld Place with them. It's why Hermione had to ...
