The Old Town Detectives. The Paintings of the Brotherhood of Blackheads

Old Town Detectives is a middle-grade series that takes readers to the medieval streets of Tallinn. In its first volume, 12-year-old Rebeka is with her dad at his company Christmas party, which is held at the historical House of the Brotherhood of the Blackheads. Wandering away from the boring event, she goes upstairs to the second floor and meets 13-year-old Gregor. The kids hear mysterious footsteps and spot black-hooded ghosts. When the two find identical notes in their pockets after returning home, they embark upon an adventure, the likes of which they could never have imagined.
