"Spare a copper for our cause?" the girl with the coin cup asks, her voice weary. "I can spare more than that," I say. I reach into my purse and giver her what real coins I have, and then I press my hand to hers and whisper, "Don't give up," watching the magic spark in her eyes. "The tragedy of the Beardon's Bonnet Factory!" she shouts, a fire catching. "Six souls murdered for a profit! Will you let it stand, sir? Will you look away, m'um?" Her sisters-in-arms raise their placards again. "Fair wages, fair treatment!" they call. "Justice!" Their voices swell into a chorus that thunders through the dark London streets until it can no longer be ignored."
