Slow Acting

Bad news, Mr. Harper: You’ve just consumed the poison I poured into your soup. The badder news is, it’s extremely slow-acting. You probably won’t even feel the initial effects for 10 to 20 years; after that, it’s still rather subtle. But won’t it be torture, knowing it’s creeping through your bloodstream over the next five or six decades? Which, given your current age, won’t shorten your lifespan. All the better! You’ll be on your deathbed—hopefully not till your mid-90s or more, to extend the torture—realizing your enemy got you. Oh, and there’s no antidote. Have a good life, Mr. Harper.
