my perforated machine tapes, but I could certainly encode his name. Then we could use a machine to do some pattern matching. Should something unusual come up, and should it match one or more of the names on the list, why we might then have a closer look at those individuals with human assets. We could just hand that off to MI5. It’s what they do for a living, yes?”
“Something tells me I would hate to have my name on such a list. It’s damn uncomfortable.”
“I agree, sir. Most things having to do with war are somewhat unsavory, but we muddle through.”
“War? You make it sound as though we are at odds with our own people here, Turing.”
“We will be, sir. Why do you think we even have an organization like MI5 in the first place? Yes, they run down foreign agents on British soil, but they keep an eye on the rest of us as well. If it were to be learned that one of these men on our list does something… compromising, then he becomes an enemy of fate and time as it were. If you mean to set this watch on the history, then you’ll have to be prepared to do some unpleasant things, Admiral. Suppose we suspect a man on this list for some reason—say he’s been reported captured by the enemy. He was supposed to be dead, and we all know dead men tell no tales. Yet now he’s alive, a bit of a zombie, eh? Now he can tell tales. Loose lips sink ships, to put it plainly.”
“Zombie?”
“A Haitian word for an animated corpse, sir, brought back to life by witchcraft. I use this metaphorically, but it’s a perfect image for what these men actually are, and it gets worse. Any one of these walking dead men could do something significant, and they could also have sons and daughters who might do very much more. The cancellation of Operation Jubilee is just a small part of the picture, sir. Geronimo has upset operations all through the Med and also in the Pacific. Our point of divergence is getting quite wide now, and our list will be very long indeed. The more time that passes the worse things might be.”
“Damn confounding business, Professor. The more I think about it, the more impossible it seems. There were German soldiers who might have died if these cancelled operations had gone forward. How in the world do we sort them out? There were Italian ships tangling with Geronimo in the Med, and now the Japanese. Our list now grows to a point where it becomes truly daunting, perhaps impossible to even attempt.”
“Right, sir. It’s also a rather dark feeling to think the history may now be playing out in a way it was never meant to—at least from the perspective of the men aboard Geronimo. As you suggested earlier, they have a unique position of knowing what happens in the decades ahead. Why, they’ve most likely got boxes and boxes of files on it all—enough to fill a thousand libraries. Should we be vigilant? Of course we must, but here’s the rub, sir…How do we know if anything has been changed, and what effect it might have had on the course of events? We don’t sit on the top of the hill like they do. We just see this particularly unpleasant gully we’ve blundered into with this bloody war. ”
“Good point, Turing. We might ask the Japanese if they feel their plans have been changed by this ship. I think we both know how they would answer.”
“Right sir, but we don’t know what was meant to be, or what may have changed. Was America meant to declare war in September of 1941? This ship had an awful lot to say about it. It’s very frustrating, sir. Think of it like a good book we’re set to revise. We want it all to turn out well, with our Ts crossed and Is dotted. Yet here we are stuck in the early chapters. What we need now is some way of knowing how the story was supposed to end, yes? Only then can we decide what to do about this particular chapter and the men that live in it. Some changes may be for the good as we see it. Suppose this Dieppe raid was a bloody disaster? In that light its cancellation may weigh in as a benefit. Does that make any sense, sir?”
“It makes a good deal of
