The Mystery of Tempelhof: France in the year 1318. The young healer Prisca von Speyer leads a quiet, secluded life on her father-in-law's estate, a landowner, in the heart of Provence. Her husband was a member of the Templars and has disappeared after their violent dissolution. What no one suspects: Prisca guards a relic that was originally hidden in the order's house in Tempelhof, near the town of Berlin. Prisca knows that the relic will not remain safe in Provence for long. She has only one chance; she must find the seven Templars who are hiding somewhere to protect the treasures of the order.
