Inquisitive Rogue = Narc

There's nothing I love more than playing a class the exact opposite of the typical archetypes. 

Inquisitive Rogue is my favorite subclass for this, one of my characters is Inquisitor Malum, an Imperial Narc who sniffs out dissidents and erases political fiascos. 

Does anyone else have an atypical way to play rogues?

A Dart-throwing Mastermind Rogue with the Harper Teamwork feat. Lets the Rogue take the Help action from 30 feet away, and and give disadvantage on it's next saving throw, all for just the cost of your bonus action. You can pair this with Cunning Strikes to get some nasty effects or let one of your battlefield controlling teammates hit them with a strong control spell like Hold Monster or Banishment.

A Rapier-wielding Arcane Trickster Rogue with a 1 level Fighter dip. Take Zhentarim Ruffian for your Origin feat.  From Fighter grab Blind Fighting and shield proficiency, then take Fog Cloud as a spell choice at Rogue 3. For feats, grab Sentinel and Zhentarim Tactics. Cast Fog Cloud on the enemy, then run right up to him. He can't disengage or run away because of Sentinel, you have constant advantage in the cloud due to having Blindsight from your fighting style, and if they do manage to hit you or a nearby ally, you get an Opportunity Attack with advantage where you get to roll your damage twice and take the highest (including your Sneak Attack dice) thanks to Zhentarim Ruffian. On your own turn, you can use Booming Blade for extra damage and that nice extra damage on movement rider.  I call him my Arcane Stalker.
