I am too suspicious. Are they sure this man died from the cause he is reputed to have passed away from? It makes me wonder if he wasn't purposely exposed to something toxic to cause him to become ill and pass away.

It's just that it's such a coincidence that there's suspicion of such things surrounding others in his family. And when things are too much of a coincidence to be a coincidence they usually aren't. Was he getting in the way?
