Harley's Little Black Book #1

A group of thugs plans to kidnap Wonder Woman by throwing sleeping gas canisters into her apartment. Harley Quinn gets word of this attack, and decides to "save" Wonder Woman. Disguised as a flower delivery person, Harley goes to Wonder Woman's apartment and throws a gas canister inside. Wonder Woman, wearing a bath robe, is knocked out quickly. Harley then undresses Wonder Woman's costume, and puts it on herself!
