Leak is usually from the quarter windows. Easiest way to check is to hop in the boot with a torch. Get someone (that you can trust) to close the boot lid and squirt all around the rear windows and boot with a water hose. You should be able to see where the leak is coming from using the torch. In particular, look at the area near the top of the wheel arches and towards the front of the car.
