The Three Investigators - Die Drei Fragezeichen

My absolute favorite kid detective stories as a kid was The Three Investigators, or Die Drei Fragezeichen. The Three Investigators, as the card says, were Jupiter Jones, Peter Crenshaw, and Bob Andrews (Justus Jonas, Peter Shaw und Bob Andrews).  I think there was something about these seemingly normal boys and their adventures solving mysteries and crime that totally captivated me.  They were stationed out of Jupiter’s aunt and uncle’s junk yard, where they had built a secret headquarters out of an RV left in the yard.  Jupiter  invented lots of little devices with the junk in the yard, like communicator devices, etc. And they were sponsored, so to speak, by Alfred Hitchcock (though it took me years to catch on to who he was).
