When Thursdays begin arriving out of order in the town of Blackwater-on-Mere, archive assistant Mabel Quince discovers that municipal paperwork is a far more dangerous form of time travel than anyone had the decency to admit.

This series leans into mystery, mild comedy, and temporal inconvenience:

• memos that arrive before they are written
• a detective who is only dead on alternate days
• a railway platform with strong opinions about punctuality
• the quiet suspicion that local government was never meant to have access to paradoxes
