Once you accept the quest, head over to the Merchants Guild in Hightown at night and confront a Templar Lieutenant who was investigating the death of one Ser Karras (if you did not kill Karras and the Templars yourself, they were killed while following the false trail you sent them on).
Choosing any option from the dialogue will result in the Templars attacking your party.
The fight is not much different from any other templar encounter; a Commander to regenerate everyone's health while eating damage and a Templar Hunter to one-shot your team. Stun and kill the Templar Lieutenant, then kill the archers, as taking out even the initial two will spawn the Hunter. Frost and spirit elements do the most damage. Kill the Hunter with your strongest attacks, then clean up. If necessary, kill the Invisible Sisters skulking around Hightown beforehand and retreat from the Merchants' Guild commons to get a break in combat between waves. You may or may not get a drop out of combat, but you'll get the templars spaced out enough that the Lieutenant and Hunter won't fight together
