Crimes in the Moorsteiner Forest

Tim, Karl, Gaby, and Klösschen are at the Moorsteiner Lake for a swim when Karl receives a mysterious distress call that rapidly spreads across social media. A photo shows a gagged man who has pushed his blindfold up slightly for a quick selfie. The image is accompanied by an urgent "Help." Could this be a bad web joke? Tim recognizes the background of the shot: it is clearly the fisherman's hut of an old acquaintance right here at Moorsteiner Lake! TKKG rush to the hut to rescue the victim and find themselves embroiled in a precarious case whose implications they could not have anticipated.

The Secret in the Hunting Lodge

The Kapper family from Kapperstein wants to sell their hunting lodge, and Klösschen's father is one of three interested buyers. Tim, Karl, Gaby, and Klösschen are excited to accompany Mr. Sauerlich during the viewing weekend. The first item on the agenda: a demonstration hunt in the accompanying forest. When a horse is struck by a shot and falls, the host suffers a severe bruise on his leg. Was it a stray shot from a shotgun, or perhaps an assassination attempt? What is the connection to a similar hunting accident involving General August Kapper of Kapperstein exactly one hundred years ago? What mysterious role did the general play in World War I? And where has one of the three potential buyers suddenly disappeared to? TKKG begins their investigation and uncovers a peculiar riddle that no one has been able to solve for a hundred years.

Deadly Clarinet

Gaby's idea to organize a flea market for a good cause with the entire class 9b is a resounding success! Class teacher Dr. Waldemar Schindler rounds up the earnings, and everyone is very proud: Class 9b will be able to ceremoniously present 1,000 euros to the non-profit organization "Education for Everyone!" the very next day! But the next day, the money from the sale has vanished.
