Puti Derrell likes running at midnight. During lockdown it was safe but now lockdown is over and Porohiwi doesn't feel safe anymore - especially when she discovers her estranged grandfather has been murdered. Puti's already got a lot on her mind. She's the new guardian of ten-year-old Bella Rose, who wants to be a private investigator when she grows up, and the new owner of Mainly Crime, a secondhand bookshop in a town she hates. And her grandfather's death is not straight forward - he was discovered with a Judas mask on his face, and a mask of Mary Magdalene has vanished. And then there's another death close to home ... and matters of blood takes on a whole new meaning as Puti and Bella Rose try to solve the murders and who took the mask.
