TKKG Junior 17 - Oskar in the Trap

In Gaby's neighborhood, pets have recently been disappearing. Each time this happens, a white delivery van is seen in the area. Could the animals have been kidnapped? Strangely, no ransom is demanded. TKKG takes on the case and initially flounders. When TKKG helplessly watches as Gaby's dog Oskar is also abducted one afternoon, it's high time to catch the unscrupulous animal catchers. But where is Oskar? And how will they find the culprits? With courage and cleverness, TKKG eventually gets on the right track.
