The man with the yellow sneakers

Life in Coolum Beach is never boring for the Kuhlmann family. Despite occasional bouts of homesickness, they enjoy living in this Australian coastal town, especially since they have found great new friends among humans and dogs. But they are horrified when somebody discovers a body in a strange outfit. Why does the dead man wear a flipper on his right foot, more than a kilometre away from the nearest beach? The victim was a seventeen-year-old vegan, committed to animal welfare and nature conservation. Why was he killed? Coming across some creepy people, the Kuhlmanns are starting to feel a bit anxious. And somehow, they become entangled in dangerous events that are connected to the mysterious murder case.
