The Wallace Bone Templar Hunt can be found in the southwestern corner of the Westminster borough. The restricted area covering this is in a lengthy alleyway guarded on at both ends by Blighters. The target himself patrols the length of the alleyway back and forth.

The good news is that the optional objective fort his memory also gives you a hit as to the easiest way to complete it – using a hiding spot! At around the midway point of the alleyway you’ll find a curtained shack with a stationary Blighter opposite. When the target is away, and none of the Blighters at either end of the alley is looking, drop down and assassinate this guard before quickly turning around and hiding behind the curtain.

The target patrols up and down the alleyway (left). Use the curtain hiding spot to take him down (right).

Wait for the target to return and he should check out the body. At this point, simply whistle him over to the curtain for a hiding spot takedown.

Once you have killed the target, escape from the restricted area to complete the activity.
