That was the cruelest irony of all, that they had undone the future out of a desire to help—Eileen’s giving Binnie aspirin to bring her fever down and tearing up the letter to keep the children from drowning, Mike’s unfouling the propeller because he couldn’t stand the thought of fourteen-year-old Jonathan being killed and pushing the two firemen away from the collapsing wall.

Even the act which had set it all in motion had come not from malice but from an innocent desire to see something beautiful. It seemed impossible that compassion and kindness should be the weapons of destruction, that just the opposite should be true. It was true that in a chaotic system, good actions could have bad consequences, but why—?

Polly had the sudden feeling that she knew the answer to that, that it lay just out of reach, like a word on the tip of one’s tongue. She stopped on the street and stared into the blacked-out darkness, mentally reaching for it. It had something to do with Alf and Binnie blocking Eileen’s way, and the shelter at Holborn—

A siren not twenty feet away screamed, and she jumped, startled and then annoyed at the interruption of her train of thought. It had had something to do with the shelter at Holborn … no, that couldn’t be right, Alf and Binnie had been at Blackfriars, not Holborn, but it was Holborn, she was certain of it. Holborn and Mike’s missing the bus and …

No, it was gone. And this raid wasn’t going to be one of those times with twenty minutes from alert to bombs. She could already hear planes, and she should get the aspirin to Mr. Dunworthy as soon as possible.

But when she arrived home, he was asleep. Alf was, amazingly, sitting at the kitchen table doing his lessons. Whatever he’d done to the tube station guard or the truant officer must have been something appalling even for him.

Binnie was reading aloud to Eileen from the book of fairy tales. “ ‘You must be home before the clock strikes twelve,’ the fairy godmother told Cinderella, ‘or the spell will be broken.’ ”

“Should I wake Mr. Dun—Mr. Hobbe and give him the aspirin?” Polly interrupted to ask Eileen.

“No, sleep is the best thing for him.”

“What does that mean, the spell will be broken?” Binnie asked. “What happens when it’s midnight?”

“I’ll wager Cinderella blows up,” Alf said. “Boom!”

“Go on to bed, Polly,” Eileen said. “You look done in.”

I am, she thought. We all are. And midnight’s coming.

She went to bed, but sleep was out of the question, and when she heard Mr. Dunworthy coughing in the night, she got up quietly, fetched a glass of water, and took it and the aspirin in to him.

He was sitting up in bed. “Oh, good, it’s you,” he said when she switched on the lamp beside the bed. “I need to tell you something.” And whatever it was, it was more bad news, because he had the same hopeless look he’d had in St. Paul’s and in the pub.
