In 1994, the Swedish engineer, entrepreneur and adventurer Malte Stierngranat was buried in a pyramid that he had designed himself. The pyramid was erected almost half a century prior to his death, on a piece of land that Stierngranat bought close to his home. He also had his own personalised coffin built, which he always took on his trips, even shorter ones.
Carol is contacted by the cleaner George in the middle of a cold Swedish winter. This leads her on a journey in which she has to delve into Malte Stierngranat’s illustrious life and his legacy. George is the cleaner and caretaker of Malte Stierngranat’s son, Erik, and his family. The entire family, which is one of the wealthiest in the city, has gone missing. George is left without a job, and without a final paycheck. He’s also worried about what has happened to the family.
When Carol believes that her investigations have led her to a dead end, the boyfriend of Malte Stierngranat’s granddaughter is found dead in the family’s old barn. The police investigation shows that his body has been lying in the barn since the family’s disappearance.
