Mrs. Martin's Incomparable Adventure

Then proper, correct Miss Violetta Beauchamps, a sprightly young thing of nine and sixty, crashes into her life. The Terrible Nephew is living in her rooming house, and Violetta wants him gone. 

Mrs. Martin isn’t about to start giving damns, not even for someone as intriguing as Miss Violetta. But she hatches another plan—to make her nephew sorry, to make Miss Violetta smile, and to have the finest adventure of all time. 

If she makes Terrible Men angry and wins the hand of a lovely lady in the process? Those are just added bonuses.

Author’s Note: Sometimes I write villains who are subtle and nuanced. This is not one of those times. The Terrible Nephew is terrible, and terrible things happen to him because he deserves them. Sometime villains really are bad and wrong, and sometimes, we want them to suffer a lot of consequences.
