Under the table

Leshilar reaches out and seeks hidden deals among the people he sees in front of him, searching for something sinister, threatening, or corrupt. 

A caster can scan the minds of any person within about thirty feet, searching to see if they have recently made a deal of some negative value. It can be a wager with a god for a high cost, a corrupt monetary exchange between two public officials, blackmail, a trade of lives, or anything the dungeon master deems a threat to the party or those the party cares about. The target must succeed on a INT saving throw (Spellcaster's DC+ their player level after level two, so level three would be DC+1, level four DC+2...) to escape revealing this information to the caster. (A save success means no information is gained, and the target can make an arcana check to detect the attempt). On a fail, the target must reveal the contents of the deal to the caster, unknowingly.
