...a multiple definition, perchance?

Or rather, multiple devices.

Actually, I think it's a single cryptic definition, the answer being RED HERRINGS.

[rab] Very good! Although it is actually a strict Ximinean clue. Details: The last four words are the cryptic part (RE D HER RINGS); the rest of the clue up to "...account" is the definition.

I probably would have noticed that if I wasn't (supposed to be) working at the same time! In the meantime, this has reminded me of one that I've wanted to clue for a while:
This clue might be: "500. Precedes solid containing volume of mute's heart"
