Professor Craig Kennedy is a scientist detective at Columbia University. He uses his knowledge of chemistry and psychoanalysis to solve cases, and uses exotic devices in his work such as lie detectors, gyroscopes, and portable seismographs.

"Gold of the Gods" – A Professor of Archeology from the University asks detective Kennedy's assistance in order to find a thief who stole an ancient Inca dagger from the artifacts found in a recent dig. While the two are still in conference, a word comes out that a wealthy Peruvian has been killed, and the Inca dagger has been used as a weapon.
