clues galore, but they haven't got a millo's worth of results so far." "What? You mean to say it's a problem they can't solve?" "That they haven't, to date," he corrected, absently. "And that 'gives me furiously to think'." "It would," she conceded, "and it also would make you itch to join them. Think at me, and it'll help you correlate.
