I appear to have a water leak into the boot, it looks to be coming down the drivers side at the very rear.

When I have removed the hatch to get to the drivers side rear light, looking up there is water droplets, so it seems to be coming in higher up than the rear lights, anyone else had this issue? The only thing I can think is either the bolts that hold the tail gate gas strut bracket, or the rubber boot at the top which lets the wiring into the boot lid is somehow leaking but if it was the rubber boot I would have thought it would end up running down both side and be evident in the roof trim and it isn't,
