says "Maybe but it did not work out that way, everyone who learned Morse knows who was on the ship, anyway they are all still here so what does it matter? And M'Clare would not have picked people who were going to funk it, after all."

My chair gets a kick on the ankle which I suppose was meant for B; Eru is six foot five but even his legs do not quite reach; he is the only one of us facing the door.

M'Clare has somehow shed his weariness; he looks stern but fresh as a daisy. There are four with him; Ram and Peter looking serious, one stranger in Evercleans looking determined to enjoy the party and another in uniform looking as though nothing would make him.

M'Clare introduces the strangers as Colonel Delano-Smith and Mr. Yardo. They all sit down at the other end of the table; then he frowns at us and begins like this:

"Miss Laydon is mistaken. You were not selected on any such grounds as she suggests. I may say that I was astonished at the readiness with which you all engaged yourselves to take part in such a desperate gamble; and, seeing that for the last four years I have been trying to persuade you that it is worth while, before making a decision of any importance, to spend a certain amount of thought on it, I was discouraged as well."

Oh.

"The criterion upon which you were selected was a very simple one. As I told you, you were picked not by me but by a computer; the one in the College Office which registers such information as your home addresses and present whereabouts. You are simply that section of the class which could be picked up without attracting attention, because you all happened to be on holiday by yourselves or with other members of the class; and because your nearest relatives are not on Earth at present."

Oh, well.

All of us can see M'Clare is doing a job of deflation on us for reasons of his own, but it works for all that.

He now seems to feel the job is complete and relaxes a bit.

"I was interested to see that you all, without exception, hit on variations of the same idea. It is of course the obvious way to deal with the problem." He smiles at us suddenly and I get mad at myself because I know he is following the rules for introducing a desired state of mind, but I am responding as meant. "I'll read you the most succinct expression of it; you may be able to guess the author."

Business with bits of paper.

"Here it is. I quote: 'Drag in some outsider looks like he is going for both sides; they will gang up on him.'"

Yells of laughter and shouts of "Lizzie Lee!" even the two strangers produce sympathetic grins; I do not find it so funny as all that myself.

"Ideas as to the form the 'outsider' should take were more varied. This is a matter I propose to leave you to work out together, with the assistance of Colonel Delano-Smith and Mr. Yardo. Te Whangoa, you take the chair."

Exit M'Clare.

This leaves the two halves of the table eying one another. Ram and Peter have been through this kind of session in their time; now they are leaning back preparing to watch us work. It is plain we are supposed to impress the abilities of Russett near-graduates on the two strangers, and for some moments we are all occupied taking them in. Colonel Delano-Smith is a small, neat guy with a face that has all the muscular machinery for producing an expression; he just doesn't care to use it. Mr. Yardo is taller than any of us except Eru and flesh is spread very thin on his bones, including his face which splits now and then in a grin like an affable skeleton. Where the colonel fits is guessable enough, Mr. Yardo is presumably Expert at something but no data on what.

Eru rests his hands on the table and says we had better start; will somebody kindly outline an idea for making the Incognitans "gang up"? The simpler the better and it does not matter whether it is workable or not; pulling it to pieces will give us a start.

We all wait to see who will rush in; then I catch Eru's eye and see I am elected Clown again. I say "Send them a letter postmarked Outer Space signed BEM saying we lost our own planet in a nova and will take over theirs two weeks from Tuesday."

Mr. Yardo utters a sharp "Ha! Ha!" but it is not seconded; the colonel having been expressionless all along becomes more so; Eru says, "Thank you, Lizzie." He looks across at Cray who is opposite me; Cray says there are many points on which he might comment; to take only one, two weeks from Tuesday leaves little time for 'ganging up', and what happens when the BEMs fail to come?

We are suddenly back in the atmosphere of a seminar; Eru's glance moves to P. Zapotec sitting next to Cray, and he says, "These BEMs who lost their home planet in a nova, how many ships have they? Without a base they cannot be very dangerous unless their fleet is very large."

It goes round the table.

Pavel: "How would BEMs learn to write?"

Nick: "How are they supposed to know that Incognita is inhabited? How do they address the letter?"

The Crow: "Huh. Why write letters? Invaders just invade."

Kirsty: "We don't want to inflame these people against alien races. We might find one some day. It seems to me this idea might have all sorts of undesirable by-products. Suppose each side regards it as a ruse on the part of the other. We might touch off a war instead of preventing it. Suppose they turn over to preparations for repelling the invaders, to an extent that cripples their economy? Suppose a panic starts?"

Dilly: "Say, Mr. Chairman, is there any of this idea left at all? How about an interim summary?"

Eru coughs to get a moment for thought, then says:

"In brief, the problem is to provide a menace against which the two groups will be forced to unite. It must have certain characteristics.

"It must be sufficiently far off in time for the threat to last several years, long enough to force them into a real combination.

"It must obviously be a plausible danger and they must get to know of it in a plausible manner. Invasion from outside is the only threat so far suggested.

"It must be a limited threat. That is, it must appear to come from one well-defined group. The rest of the Universe should appear benevolent or neutral."

He just stops, rather as though there is something else to come; while the rest of us are waiting B sticks her oar in to the following effect.

"Yes, but look, suppose this goes wrong; it's all very well to make plans but suppose we get some of Kirsty's side-effects just the same, well what I mean is suppose it makes the mess worse instead of better we want some way we can sort of switch it off again.

"Look this is just an illustration, but suppose the Menace was pirates, if it went wrong we could have an Earth ship make official contact and they could just happen to say By the way have you seen anything of some pirates, Earth fleet wiped them up in this sector about six months ago.

"That would mean the whole crew conniving, so it won't do, but you see what I mean."

There is a bit of silence, then Aro says, "I think we should start fresh. We have had criticisms of Lizzie's suggestion, which was not perhaps wholly serious, and as Dilly says there is little of it left, except the idea of a threat of invasion. The idea of an alien intelligent race has objections and would be very difficult to fake. The invaders must be men from another planet. Another unknown one. But how do the people of Incognita come to know that they exist?"

More silence, then I hear my own voice speaking although it was my intention to keep quiet for once: it sounds kind of creaky and it says: "A ship. A crashed ship from Outside."

Whereupon another voice says, "Really! Am I expected to swallow this?"

We had just about forgotten the colonel, not to mention Mr. Yardo who contributes another "Ha! Ha!" so this reminder comes as a slight shock, nor do we see what he is talking about but this he proceeds to explain.

"I don't
