The Secret 6

Escaping certain death in the electric chair, the enigmatic adventurer known only as King welds a disparate group of trained professionals into the crime-fighting force called the Secret 6! Their sacred mission: to destroy supercriminals whenever they surface! For their first assignment, these fighting fugitives from justice track down the sinister strangler known only as the Red Shadow. Who is he? How does he commit his scarlet slayings?

Hunted by the law for the Red Shadow's crimes, King struggles to unmask the towering terrorist, not knowing that the fiend belongs to the very organization created to destroy him! For if the ranks of the Secret 6 harbor a traitor, can it survive its first test?

The Red Shadow first appeared in the October 1934 issue of The Secret 6 magazine.
