up an acquaintance with me only last week. I should have realized—" "You certainly should have. One week. Time enough and more. By now you've been photographed, your fingerprints taken, your voice recorded and your gait studied without your knowledge. Only the retinascope is difficult, but one must risk it for a real double.
