I go on flipping the coin up and presently it drops on the floor, it is Heads this time. Tossing coins is a pretty feeble way to decide. I drop the note on the floor and take another sheet and write "YES. Lysistrata Lee." Using that name seems to make it more legal. I slip the paper in the slit and poke till it falls through on the other side of the door. I am suddenly immensely hungry and dial breakfast all over again. * * * * * Just as I finish M'Clare's voice starts once more. "It's always the minor matters that cause the most difficulty. The timing of this announcement has cost me as much thought as any aspect of the arrangements. The trouble is that however honest you are--and your honesty has been tested repeatedly--and however strong your imagination--about half of your training has been devoted to developing it--you can't possibly be sure, answering a hypothetical question, that you are giving the answer you would choose if you knew it was asked in dead earnest. "Those of you who answered the question in the negative are out of this. They have been told that it was a test, of an experimental nature, and have been asked to keep the whole thing a secret. They will be returning to Earth in a few hours' time. I ask the rest of you to think it over once again. Your decision is still private. Only the two people who gathered you together know which members of the class are in this ship. The list of possible helpers was compiled by a computer. I haven't seen it myself. "You have a further half hour in which to make up your minds finally. Please remember that if you have any private reservations on the matter, or if you are secretly afraid, you may endanger us all. You all know enough psychology to realize this. "If you still decide in favor of the project, write your name on a slip of paper and post it as before. If you are not absolutely certain about it, do nothing. Please think it over for half an hour." Me, I had enough thinking. I write my name--just L. Lee--and post it straight away. However I cannot stop thinking altogether. I guess I think very hard, in fact. My Subconscious insists afterwards that it did register the plop as something came through the slit, but my Conscious failed to notice it at all. Hours later--my watch says twenty-five minutes but I guess the Mass-Time has affected it--anyway I had three times too much solitary confinement--when will they let me out of here?--there is a knock at the door and a second later it slides apart. I am expecting Ram or Peter so it takes me an appreciable fraction of a moment to realize I am seeing D. J. M'Clare. Then I remember he is back on Earth buried in Exam papers and conclude I am having a hallucination. This figment of my imagination says politely, "Do you mind if I sit down?" He collapses on the couch as though thoroughly glad of it.
