“Mike saved Private Hardy’s life because the slippage caused him to arrive in Saltram-on-Sea too late for the bus. And I met Sir Godfrey because the net sent me through in the evening instead of the morning.” She told him about being caught by the warden and taken to St. George’s. “And because of the slippage that first time you came through, you ended up at St. Paul’s Station. Where you needed to be to run into the Wren.”
“So you’re saying slippage’s function is to bring about alterations, not prevent them? That it kept us here intentionally?”
“I know what you’re going to say, that a chaotic system isn’t a conscious entity—”
“That’s exactly what I’m going to say.”
“But it wouldn’t have to be. You thought the shutting of our drops was a defense mechanism. Perhaps it is, only not to shut off interference from the future, but to enlist it when the continuum’s threatened. If Hitler’d won the war, he’d have had time to develop the atomic bomb, and he wouldn’t have hesitated to use it against the United States and all the other non-Aryan peoples. He already had a plan in place for wiping out Africa’s ‘mud people,’ and he wouldn’t have stopped there. He could have ended by wiping out—”
“Everything,” Mr. Dunworthy said. “Gotterdammerung, the twilight of the gods. But if that’s the case, and the continuum wanted to protect itself, why didn’t it simply let us come through and shoot Hitler?”
“I don’t know. Perhaps the system only allows minor changes. Or unintentional ones. Or perhaps something else is going on in those divergence points which makes it impossible to alter them. Or perhaps we came into the picture too late. Like the Good Fairy in Sleeping Beauty—”
“The Good Fairy?”
“Yes,” she said earnestly. “She couldn’t undo the spell, she could only make it less terrible. Time travel wasn’t invented till long after the start of the continuum.
Perhaps we’re too late to completely repair it, but we can still—”
“But even if that’s true, and even if you saved Sir Godfrey’s life and Mike saved Hardy’s and I saved the Wren’s, we still altered events, and history’s a chaotic system where a good action, done with the best intentions, can have the opposite effect. How can you be certain that even if the continuum intended us to make repairs, we did? That we didn’t make things worse instead?”
“Because they were already worse.”
“Worse? What do you mean?”
“I mean, what if we’ve been looking at the war the wrong way round? What if the disaster had already occurred, and the outcome we were altering was a bad outcome?”
“A bad outcome?” Mr. Dunworthy said, bewildered.
“Yes. What if the Allies lost the war? You said there were dozens of times when the outcome balanced on a knife’s edge, like in that old saying, ‘For want of a nail, the shoe was lost, for want of a shoe—’ ”
“—the horse was lost.”
“Yes, and because of that, the rider and the battle and the war were lost. There were scores of times in World War Two like that, when if things had gone even slightly differently, we’d have lost. Well, what if we did lose?” she asked. “What if your Wren was killed in Ave Maria Lane and Sir Godfrey was killed in Bristol and Eileen’s bombing victim died in the back of the ambulance because they couldn’t find a driver and Hardy ended up in a German POW camp and they lost the war?”
“But then time travel would never have been invented. Ira Feldman—”
“No, because the continuum’s a chaotic system, which means time travel was already a part of it, and they hadn’t lost it. Because you’d come and run into a Wren and set a cascade of events in motion. And Mike was part of that cascade, and our being stranded here.”
“We’re the horseshoe, in other words.”
“Yes—”
“And you’re saying we waltzed in, tightened a few nuts and bolts, and won the war?” Mr. Dunworthy said. “Historians as Little Miss Fix-Its? My dear, history’s a chaotic system. It’s far more complicated than—”
“I know it’s complicated. I’m not saying we won it. And I’m not saying your Wren or Hardy or Sir Godfrey or Alf and Binnie or whoever it is they and Eileen treated on the twenty-ninth was who won it either. Or even that saving them was what tipped the balance. It may have been something else altogether—Marjorie’s deciding to become a nurse, or one of the FANYs I worked with borrowing my dance frock, or Mike’s nearly colliding with Alan Turing. Or something we don’t even know we did—our stepping ahead of someone onto an escalator or hailing a taxi or asking for directions. Mike might have done something in hospital, or Eileen might have affected one of her evacuees. Or I might have taken too long to wrap a customer’s parcel and delayed her five minutes, so that she missed her bus, or got caught in the tube when the sirens went.”
“But you think whatever that action was, one of us did it,” Mr. Dunworthy said. “And it was one of us who won the war.”
“No,” she said, frustrated. “I’m not saying that either. No one person or thing won the war. People argue over whether it was Ultra or the evacuation from Dunkirk or Churchill’s leadership or fooling Hitler into thinking we were invading at Calais that won the war, but it wasn’t any one of them. It was all of them and a thousand, a million, other things and people. And not just soldiers and pilots and Wrens, but air-raid wardens and planespotters and debutantes and mathematicians and weekend sailors and vicars.”
“Doing their bit,” Mr. Dunworthy murmured.
“Yes. Canteen workers and ambulance drivers and ENSA chorus girls. And historians. You said no one can be in a chaotic system and not affect events. What if your—our—coming to the past added another weapon to the war, a secret weapon like the French Resistance or Fortitude South?”
“Or Ultra.”
“Yes,” Polly said. “Like Ultra. Something which operated behind the scenes, and which, combined with everything else, was enough to avert disaster, to tip the balance.”
“And win the war,” Mr. Dunworthy said softly.
