Seven Days

The magical world is being terrorised by a string of brutal, baffling murders. Murders that take place inside locked houses, and apparently, in front of highly trained Auror guards. Murders that are announced a week in advance by a countdown timer that is delivered to each victim by owl post.

When the case takes a personal turn, Chief Auror Potter enlists the help of Special Branch, an elite unit of ex Death Eaters who are paroled to help the Aurors when needed. Unfortunately though, Special Branch don't always play by the rules. Antonin Dolohov is confident he can solve the case, but he has one condition. He will only help if he can work alongside Hermione Granger.

Hermione agrees. It's only a week, after all. Seven little days. Seven days to solve the most baffling murder case in history. Seven days to work with a man who tried to murder her twice in the past. Hermione is about to find out that a lot can happen in seven days.....
