Sounds like your wife's been buying a lot of umbrellas lately and you're getting a bit worried. Ha, ha.
No seriously though it did remind me of a story that happened here in the U.K. a while ago. Someone being stabbed by a poison umbrella by a russian spy.
I bet there's plenty on it under ninjutsu or something similar.
Perhaps Nialls wife is saving up umbrellas for a rainy day?
