Officious Interrogation

Some abilities trigger "whenever you sacrifice a Clue". Those abilities trigger whenever you sacrifice a Clue for any reason, not just to activate a Clue's activated ability.

If an effect refers to a Clue, it means any Clue artifact, not just a Clue artifact token. For example, you can sacrifice Wrench to pay for Alquist Proft, Master Sleuth's activated ability.

You choose how many targets Officious Interrogation has and what those targets are as you cast it. You can't choose the same target more than once. It's legal to cast Officious Interrogation with no targets, although this particular option should be placed under some serious scrutiny.
