Water Leak in the Basement is a written note found in Dishonored 2.
My faithful Jaime,
I have discovered a leak in the basement. No, don't go and fix it, good man. There is a bloodfly nest near it and the situation is altogether too dangerous. I'm sure another solution will present itself, once I think on it a bit. Unfortunately I've a lot on my mind right now.
In the meantime, let's seal up that portion of the basement to close off the danger. The water is likely to rise a bit, so be sure to keep the drain stoppers open.
How's your leg? If it's still bothering you, I can have the doctor 'round to give it a look.
