The Wolves of Baskerville (слэш)

John Watson is an army doctor, turned bored civilian.
One day he gets a mysterious phone call from a man who offers him a large sum of money to take care of a wounded omega.
As omegas are very rare and John has a certain sense of adventure, he accepts the offer.
This brings him to an old mansion outside the town of Baskerville, where he might get more than he bargained for.
