Lasso of Hestia: Wonder Woman's completely indestructible weapon, with the ability to force anyone it captures to obey the lasso's wielder and tell the truth. She successfully wielded it against Steve Trevor (in order to get the experienced spy to tell her the truth), General Ludendorff (in order to prevent his escape and kill him), Ares (in order to keep up with the violent God of War in battle), Doomsday (in order to temporarily restrain him, while Batman weakened him, and Superman delivered the finishing blow), and the resurrected Superman (in order to restrain him until the post-mortem amnesia wore off).
Later, as a healer tended to Diana's battle wounds, she noted with confusion that Diana's wounds had healed completely. Diana then visited Trevor in his cell, asking him about the outside world. Due to his words, Diana decided to sneak him off the island and confront Ares herself. She snuck into the island's tower and stole the god killer, along with an Amazon shield, the Lasso of Hestia, and a special set of battle armor. She broke Trevor out of his cell and took him to the island's dock, where she was intercepted by her mother. To her surprise, Hippolyta allowed Diana to leave, gifting her Antiope's tiara. She then warned Diana to be careful, mournfully telling her that the world of men did not deserve her.
In 1944, Gaines and Marston signed an agreement for Wonder Woman to become a newspaper strip, syndicated by King Features. Busy with the newspaper strip, Marston hired an 18-year-old student, Joye Hummel, to help him write comic-book scripts. Joye Hummel, now Joye Kelly, turned 90 this April; in June, she donated her collection of never-before-seen scripts and comic books to the Smithsonian Libraries. Hiring her helped with Marston’s editorial problem, too. Her stories were more innocent than his. She’d type them and bring them to Sheldon Mayer, Marston’s editor at DC, she told me, and “He always OK’d mine faster because I didn’t make mine as sexy.” To celebrate syndication, Gaines had his artists draw a panel in which Superman and Batman, rising out of the front page of a daily newspaper, call out to Wonder Woman, who’s leaping onto the page, “Welcome, Wonder Woman!”
