Extract Knowledge

By touching a recently deceased corpse, you gain
one specific bit of knowledge from it that was
known to the creature in life. You must form a
question in your mind as part of casting the spell;
if the corpse has an answer to your question, it
reveals the information to you. The corpse
doesn't need a functioning mouth to speak its
answer; you receive the information
telepathically. The spell compels it to answer,
regardless of it's relationship to you.
