So the charm's page states that the charm is ""An immensely complex spell involving the magical concealment of a secret inside a single, living soul. The information is hidden inside the chosen person, or Secret-Keeper, and is henceforth impossible to find — unless, of course, the Secret-Keeper chooses to divulge it. As long as the Secret-Keeper refused to speak, You-Know-Who could search the village where Lily and James were staying for years and never find them, not even if he had his nose pressed against their sitting room window!"
Living...
But what if the Secret-Keeper dies before the people involved in the secret they are keeping do? Will the secret just go to the grave with the Secret-Keeper and be therefore impossible to reveal to anyone? Or can another
Secret-Keeper be chosen?
Also, poor Voldy doesn't even HAVE a nose, the Charm page quote should say 'nostrils' lol
