Emperor of the Yellow Death (#27):
An exotic woman of the East, as deadly as she is beautiful… servant to a horrific criminal genius! More ruthless than any of his Mongol ancestors, Wang-ba stages a villainous uprising designed to enslave all of America. Richard Wentworth, alias the Spider, faces hidden death-traps, hordes of maddened gunmen and… man eating turtles!
Slaves of the Burning Blade (#91):
Was a foreign sabotage ring responsible for this newest series of terror… or was that what some hidden menace wanted everyone to think? Only the Spider recognized the truth… that the man behind the scenes was the criminal genius known as The Knife! Wentworth is hounded by the law, as well as a vigilante band, the Knights of Liberty!
