The Insider

"The Insider"

A mysterious underworld mastermind so named because the crimes for which he is responsible invariably require specialized knowledge, such as a safe combination, available only to an "insider." Apprehended by Superman in November-December 1951, he is exposed as Ray Curtis, the publisher of the Metropolis Daily Dispatch (S No. 73/3: "Perry White vs. Clark Kent!"). (TGSB)
