5e does have a couple of "detect lie" spells - Zone of Truth, which forces people to speak the truth on a failed save, and detect thoughts (as it is difficult to lie without thinking about the truth you are concealing). Spells like Charm Person, Dominate Person, and Suggestion could also compel the truth, though often with negative consequences (when the spell wears off they realize that they've been manipulated).
Detect Thoughts actually is in this game. I have a scroll for that as well.
