A Hunch...
Hmmm...i was scanning through CoS yesterday, thinking about something that had been revealed before..that a small detail learned in book 2 will contribute to book 6 (sorry if theres a similar thread like this! i didnt see one in the first two pages), and i think i might've figured it out...
When harry and ron impersonated crabbe and goyle, and spoke to malfoy concerning ministry raids, malfoy revealed to them that they have a hidden chamber in their house that contained numerous dark arts stuff. putting two and two together, the conclusion that voldemort's journal came out of that chamber leads me to the future conclusion that mr malfoy took all of voldy's posessions for safekeeping after he was defeated by harry. dubledore quotes that "one must hope that no more of lord voldemorts school things fall into innocent hands. the consequences for the ones responsible..would be severe..."
just an inking hunch. any comments? other possibilities? questions? agree or disagree?
