Almost but not quite

It’s been a long time since it has even came close to being in my grasp. Not even close to being in sight for any of us really. To be honest with you, its been about ten years or more we've suffered this, and I'm not sure if I can take much more of it. If I’d killed him I’d have been out by now. Oh! I have thought about it believe me, and I'm not a violent person by any stretch of the imagination. On more than one occasion, I have lay awake staring at the ceiling praying and plotting. My eyes going mad with itch due to my allergies and the scent of vanilla for the oil burner my wife had lit earlier wasn't helping any. I would say that to date, I have gone through the full alphabet in the Encyclopaedia of murder, thinking of ways to do it. Everything from Arsenic poisoning to Zombie slaying, only problem being I don’t really know any Zombies.
