Quest starts on Caladan, all west from AP. Stay away from the pool shark, instead keep going west, there's a climbable cliff or something. Exploring there you'll find some bushes and a cave system with a pushable button that takes you into the lair of some smugglers. To the northwest behind another pushable switch or button is the spy, his instructions are pretty straight forward.
Completion grants you 300k solaris and 1 qp.
