The whole clue is the definition (& lit or double definition).
How the clue works
Nice one, this is a whole-clue pun. Remember "shop" can mean to grass someone up, so an "informer" is essentially a shopper. The surface reading, "Threat to informer?", plays on that double meaning — it's cheekily warning the informer to keep shopping (informing) until they drop, giving you SHOP TILL YOU DROP.
