'Reunited': 'Blood Type' by Simon Guerrier

Busier than ever with so many cases, Sarah has little time to write up her cases for publications. But taking shortcuts risks making mistakes, as a journalist and as an investigator.

When an old adversary reappears, the pressure reaches boiling point. But can Sarah rely on her closest friends in this crisis?
