Help! Brick loose in external leaf of cavity wall

[WWilts]

Demolishing attached garage tomorrow. Original external wall will be exposed. 

 

Problem: One brick is completely loose in that external wall. It can be picked out, and anyone can peer into the cavity of the wall. Brick inner leaf seems ok. 

The loose brick is also damaged, with a chunk missing. There is no mortar at all on any face of the loose brick. It just sits on the brick below, as if on a shelf. Don't know the origin of this problem.

 

What's the solution?

Is the solution as simple as putting in a new brick with mortar around it?

Seems so, one trick to fill the top of the brick at the end, is to use a trowel that has level mortar on it, slide it into the gap, then use a second trowel to cover the hole and slowly slide out the first trowel
