Gregor, Rebeka, and Lota make up the “Seers’ Guild” – a club that has already solved several strange mysteries in Tallinn’s Old Town. Just as they decide to accept two new members – Markus and Kaspar, who helped them on their last case – the group receives a letter asking them to help rid the Canadian Embassy of a ghost. A quick Google search shows it’d be hard to find a more chilling ghost-woman than the one in that building on Toom-Kooli Street. Luckily, the detectives are lent a hand by Gregor’s aunt Marju, who knows how people used to expel poltergeists and what to do when modern-day suspicions arise.
