Daryl and Glenn in a past life during the Korean War. AU without zombies. M*A*S*H characters and other WD characters appear.
Thomas isn't the only homosexual at the Abbey. Daryl is on the estate and there's a new Korean footman nearby. This is an AU without zombies. DA characters and events are referred to but this is mostly a retelling of WD in late Edwardian England.
Don't let the title turn you off. It's not a total shag-fest. A lighter look at Snape and Hermione in various situations.
