Sure thing – hide it in a hollowed‑out book of boring facts and call it a “history of the alphabet.” The thief will be too busy staring at the word “G” to notice the secret pocket.

You’re right, a sharp thief will skip the “G.” I’ll give you a two‑step plan: first, plant a decoy in the obvious spot – a plain, nondescript jar labeled “Do Not Open” – so the thief gets a taste of disappointment. Then stash the real loot in a place they’d never think to look – like the hollow space in the underside of a broken floorboard, marked only with a tiny, almost invisible sticker that reads “Hidden.” That way the thief’s eyes run right past it, and you’ve got your secret spot still safe.
