“No, stay here till the nurse comes back,” Eileen said. If the nurse didn’t bring any information, they could send her to surgery. “Where’s Alf?”

“I dunno,” Binnie said. “Me and ’im split up. Do you want I should go look for ’im?”

“No.” Eileen grabbed her to ensure she didn’t.

The nurse returned. “I spoke with the ambulance driver who brought Mr. Langby in. She said only one member of the fire watch came with Mr. Langby—a Mr. Bartholomew—and that he left as soon as Mr. Langby was safely inside the hospital.”

“Left?” Polly said, looking as though she’d been kicked in the stomach.

“Left to go where?” Binnie asked, and the nurse seemed to suddenly become aware of her presence.

“Children aren’t allowed in—” she began.

“Left to go where?” Eileen cut in. “It’s essential Dr. Cross speak with him immediately. When did he leave?”

“Over an hour ago,” the nurse said. “You’ll have to take that child to the waiting room.”

“She’s Dr. Cross’s niece,” Eileen said. “I’ll go and tell him.”

She let go of Binnie’s arm, grabbed Polly’s, and propelled her down the corridor. “Don’t worry. We can still catch him. We’ll drive to St. Paul’s,” she said. “Binnie—” But Binnie had disappeared.

An orderly was coming toward them, looking angry—no doubt the reason she’d vanished, and she’d reappear as soon as he passed. But she didn’t.

Good, Eileen thought, steering Polly through the maze of corridors, looking for something familiar to show her they were headed in the right direction. They obviously couldn’t take Alf and Binnie with them, and this way they wouldn’t have to waste time arguing with them over their staying here.

But Alf popped up moments later and said, “If you’re lookin’ for the ambulance, you’re goin’ the wrong way.”

“Where’s your sister?” Eileen asked.

He shrugged. “I dunno. We split up. Where’s your coat?”

“I took it off. Show us the way.”

“Come along,” he said, and led her and Polly quickly and expertly to the dispensary.

Agatha Christie wasn’t there, which Eileen supposed was good, considering what had happened last time, but she’d have liked to see her again now that she knew who she was. And what? Tell her how much you love her novels? London’s burning to the ground, and you’ve got to get to St. Paul’s, She pushed out through the emergency doors.

The ambulance wasn’t there.

Of course not. There were hundreds of casualties, and Guy’s Hospital’s ambulances couldn’t get through. I should have taken the keys like Alf, she thought, feeling sick, staring at the empty spot where the ambulance had been.

Polly was staring at the sky. The wall of smoke was still there, but the red had faded to a pinkish charcoal gray, and above the pall the overcast sky was beginning to show a hint of paler gray. “It’s nearly morning,” she said. “We’ll never make it in time.”

“No, it isn’t,” Eileen said staunchly. “That’s the light from the fires reflecting off the cloud cover.”
