Let's look at another clue and maybe get away from silencers and phone calls for a while:
After the murders a family friend of Nevill's handed in 2 weapons to the Police on the understanding he could not say the who the TWO men who gave them to him were. One of the weapons was the gun that is often Referred to in this case as the "unique weapon". This weapon had a type of barrel configuration that matched the mysterious burn marks on the the back of Nevill's neck. Was Nevill marched around the house with this weapon in the back of his neck?
Who were the TWO men that handed it to the family friend on this strict understanding? Can this family friend not be forced to name the TWO men by the Police?
