Spy Smasher #4

Spy Smasher uncovers a treacherous Japanese plot while eavesdropping at the embassy, learning of an imminent attack on Pearl Harbor—but before he can gather proof, he's forced into combat and must race against time in his aircraft to intercept the enemy's radio ship in the Pacific. With the nation's fate hanging in the balance, this masked hero faces Japanese operatives Kurusu, Captain Hidoo, and Osaki in a desperate bid to stop the assault.

In "The Man in the Iron Mask!" from Spy Smasher #4 (1942), Admiral Corby, Alan, and Eve tour the rebuilt Castle Fenmore when Alan saves the admiral from a deadly trap. As strange music echoes through the ruins, the admiral warns of a legendary figure known as the Man in the Iron Mask—a shadowy foreign agent said to be sabotaging American defenses. When the masked man appears, Alan transforms into Spy Smasher, only to see him vanish, leaving behind a trail of deadly attacks on the construction crew.

When German saboteurs blow up the naval docks at Rebel Point, Spy Smasher moves to stop them—but his investigation leads him to a Confederate veterans' home where the elderly Granpappy Swire makes a wild claim: the men around him aren't who they seem. As Spy Smasher digs deeper with help from Dr. Marston and Miss Eve, he uncovers a sinister Nazi plot hidden in plain sight, and discovers that Granpappy's sharp instincts may be exactly what's needed to save the coast from invasion.
