WaPo Bodensee

More than two million followers online want to see how the "Paleo Girl" at Lake Constance brings the Stone Age back to life. One morning, as Katrin Baumann—Paleo Girl's real name—tries to push a prehistoric boat into the lake, she is knocked unconscious from behind and abducted.

The body of a competitive rower who died during training has disappeared from the funeral home. His young widow, Leni Senger, is stunned.

Paul is participating in an open-water swim. In the middle of the lake, a swimmer next to him gets into trouble and dies. The deceased is businessman Max Behringer, who made many enemies with a wind farm project on the Swiss Seerücken.

"Not even two weeks," is Mechthild's prediction for the future of the WaPo couple, Julia and Jakob. In fact, the first signs of friction between the two begin to surface as they investigate the Kaltenbrunner case.

Bomb alert on Lake Constance. An unexploded World War II bomb has washed ashore and must be defused. Under the command of Matthias Krämer, the defusing of the dangerous anchor rope begins. Paul is also on site. He and his friend Matthias know each other from their time together in Afghanistan, where the two were involved in building up the local police force. The young bomb disposal expert Sven Sailer is tasked with defusing the mine. Matthias, Paul, and Sven's colleagues Alexandra Schulz and Hadi Bozkurt remain in contact with the young man via radio and GoPro video feed. As Sven takes a closer look at the mine, the unthinkable happens: it detonates. Sven doesn't stand a chance.

His death comes as a shock to everyone. A tragic accident? But then Paul and the forensic team find evidence suggesting that the apparent workplace accident was actually a murder: Someone deliberately remotely detonated the mine using modern explosives. When Julia breaks the news to Sven's wife, Steffi, the pregnant woman collapses. Nele and Paul determine that the explosives came from the ordnance disposal unit's armory in Friedrichshafen.

Mechthild lets Nele and Jakob—whose head is almost completely shaved—tag along as she trains to become a tour guide. She gives a particularly vivid account of the story of Gnadensee. In the Middle Ages, people sentenced to death were pushed from a boat into the lake after a bell rang—with a chance to save themselves by swimming …
