LONDON—A cry of more, more, more was heard in the midnight hour Sunday, prompting police to launch a full-scale investigation. "While we don't have any leads yet, the yell clearly sounded like it came from an outsider, possibly even a rebel," said London police commissioner James Blaney. "Before I investigate further, though, I urge you to let me sink another drink, as it will give me time to think." Blaney added that if the current investigation—during which police have looked all over the world—fails to yield any real clues soon, tomorrow might be a nice day to start again. "Whoever this rebel is," Blaney said, "he clearly has got no human grace."
