The premise of The Secret 6 was deceptively simple, yet pure pulp. An enigmatic adventurer known only as King busts out of Death Row to form an anti-crime group called The Secret 6. The others include The Key, The Doctor, Shakespeare, The Bishop, and Luga, as well as numerous underworld stool pigeons and hangers-on. All are wanted. So they operate outside the law.
The work of the wildly imaginative Robert J. Hogan, who pitted his World War I flying ace, G-8, against zombies, Martians, defrosted Viking warriors, and other bizarre foes, The Secret 6 battled sinister supervillains, a Mayan Bat-Man, a giant golden alligator and other outrageous menaces. Few pulp series stretched reality as did this four-issue Popular Publications title from 1934-35. There were no limits. That's what made it a terrific read.
