The Vampire in the Basement

The tanks are old and need replacing. Blood is leaking from the ceiling again.
We used to have them in the basement, but hauling them upstairs during every flood became a hassle.
The Master has the strength of ten, but the patience of a child and the arrogance of a nobleman.
Nor do the members of his coven perform any lifting beyond coffin lids.
Labor is for us, his daytime servants.
The work is steady, and as long as we don’t complain, we live.
The forecast calls for rain.
At least all we have to haul up are coffins now.
