This requires to you speak with Slim Couldry having completed the previous two heists. Doing so will present you with an opportunity to pay ten sovereigns for the information regarding a heist which will supposedly make you legendary. Having paid the money to Slim, a new marker will become available for you to travel to on the map of Denerim: Bann Franderel's Manor.

Walkthrough
Make your way to the marker on your map and your quest log will be updated. It's a trap. You'll be required to fight your way out of the rooms whence you came, this time filled with guards and a number of traps, not to mention a couple of mages.

Result
Once you've cleared your way to the exit, return to Slim and he'll apologise most profusely and return your money to you.
