There's a killer in our midst. His foul stench wafts through your homes and cars, stinking up doorways and outdoor eating areas in town.
Back in the day he was the life of the party - everybody wanted a piece of him. But over time he became something of a pariah, frowned upon and no longer welcome in many establishments.
He's banned from workplaces, forced out on to the streets, but still a select few seek his comfort, knowing it could be a fatal dalliance but unable, or unwilling, to resist.
You'd think someone would do something about him.
His name is tobacco.
