Blonde Phantom Comics #13 (1947)

At a museum of rare antiques, priceless jewels are being prepared to be shipped to England. The curator explains to the guard that the jewels were originally presented to George Washington by British Royalists who wished to crown him King of the United States. Although Washington accepted the gift he preferred to get his power to rule from the people and set about becoming President instead of King. Fearing that someone might try to steal the jewels as they are shipped to England, the curator calls on Mark Mason to oversee their transport. The next day, Mason leaves his office telling his secretary about his next case. After Mason has left, Louise changes into Blonde Phantom to lend a helping hand. As Blonde Phantom boards the ship, elsewhere a man known as the Redcoat -- descendant of one of the men who originally presented the jewels to George Washington -- has gathered a gang to steal the jewels so that he can place them in his ancestor's tomb to restore the family honor. Aboard the ship, Blonde Phantom "accidentally" bumps into Mark Mason who tells her that he jewels are safely locked away in the purser's office. The Blonde Phantom goes down and walks in on Redcoat and his men robbing the purser's office. Redcoat knocks her out and they tie her and the purser up and flee with the stolen jewels and head off to go to the Vault of the Westminster's to leave the jewels. With the purser's aid, Blonde Phantom breaks free of her bonds and rushes after the Redcoat. On the outer deck of the ship Mark Mason spots the Redcoat fleeing with the jewels and tackles him. However, one of Redcoat's men creases Mark's forehead with a bullet and they flee in a lifeboat. Checking on Mason, Blonde Phantom is told that he overheard the Redcoat tell his men to meet him at a place called the Blue Dove. Blonde Phantom leaves Mark to get medical attention while she goes after Redcoat and his men. She arrives at the bar just as Redcoat's goons realize that they have been double-crossed by their employer. When they attack her, she beats them into submission and realizes that the Redcoat wanted the jewels for himself. Blonde Phantom turns the men over to the Scotland Yard and then rushes to Westminster Abbey where she witnesses the Redcoat leaving the jewels in his ancestors tomb. There they fight, and before the Redcoat can choke the Blonde Phantom to death, Mark and the Scotland Yard arrive on the scene. Redcoat flees to the upper level of the tomb with Mark Mason following behind. During their scuffle, Redcoat slips and falls to his death. With the jewels recovered and put on display, Blonde Phantom vanishes just as quickly as she appeared, leaving Mark to wonder who she really is.
