What is a fail-proof hiding place?

Question:For a box, roughly half a foot high, two foot long, and afoot wide. I don't wan't to bury it unless I completly have to and the only bug enough hidden compartment under drawers gets moved fairly often.The attic might be a good idea but its fairly open with no cover and would be easily recognisable. The shed rafters above the door might be a good place but if you're inside with the door closed it can be seen (its a slidy horizontal door). Any ideas?

Answers:
In your wardrobe, at the bottom, cut out the bottom part. Put your stuff in there, and get a piece of plywood that matches the rest of the inside of your wardrobe to cover it back.
