So the soldier course above a window has come away & needs repairing.
The mortar at the sides has given up & what's left is just about holding the brickwork up.
At the moment it's propped up so stop it falling out completely.
My thinking is square it up then either remove the mortar at the sides & replace it as it was originally or drill maybe 2 holes at 45 degrees through the soldier course into the bricks either side & use rods & resin to hold it up then sort out the mortar.
