You were sure that everyone in the family would be ready to grieve in public and swear how much they loved Henry. However, now it seems to you that some don't even plan to do that. It seems as if everyone's lives have become easier with the old man gone. Try to understand who and how they really felt about him. Watch what they say and turn on all your professional skills. Someone is definitely lying here!
What is written in the will is still unknown. Maybe that's a good thing, so this information won't affect your investigation. In such a high-profile case, you still want to be as professional as possible and not go down the wrong path. Try to find out from the housemates themselves, that they themselves know about the will, its latest version. Most likely, each of them knows what his chances of inheritance are.
