You see, but you do not observe.
 
--Sherlock Holmes, in "A Scandal in Bohemia"
 
 
I kept my head down as I went around the curve, hoping the pan wouldn't fly off my head. With my right hand, I steadied my quivering spaniel and tried to keep her from toppling out of the basket. Still, even one-handed, I swear I would've made the turn with no problem.
 
Except. Except the girl was standing in the middle of Maddox Street. I shouted, "Hey, watch out!"
 
Too late. I had to let go of Little Roo. I grabbed both handlebars and pulled hard to the left. I wasn't quick enough. My right pedal struck the girl's shin; we all went down. I banged my left knee. The pan clattered away and LR tumbled out of the basket. She bounced up and began barking and twirling in circles like a crazy windup toy. Overhead, bombers roared. From the ground, ack-ack guns shot defensive fire into the sky. I scrambled to my feet, rubbing my knee.
 
"Are you all right?" I yelled over the din.
 
The girl didn't answer at first. I reached out a hand to help her up. She pushed it away. "Why don't you watch where you're going?"
 
"Me? You were standing in the street! You're lucky I wasn't a bus: You would've been crushed flat."
 
Then I stopped. Pointless. It was pointless to argue. I could tell from her accent that the girl was an American. The city was crawling with them. Soldiers in uniform, journalists, navy and army officers sporting stripes and medals, young women in crisp American Red Cross uniforms. Everyone had come to prepare for the invasion of France. It was the only way the Allies could defeat Hitler and end the war.
 
I knew as well as anyone that we needed the Americans, but there was a part of me that resented these strangers. They hadn't been here during the worst of it. Three years ago, the Blitz had gone on and on. We'd lived through all-night bombing raids, incendiary bombs designed to burn London to the ground, rubble and destruction on street after street. A lot of kids had been sent to the countryside. My older brother, Will, and I had begged to stay.
 
The Americans hadn't lived through that. Compared to us Londoners, they seemed to burst with hope and energy. Maybe they just ate better. They had money to eat in restaurants, where (so we heard) you could  still get "real" food. They hadn't spent years waiting in long queues, ration cards in hand, to buy food that didn't taste much like food.
 
Latecomers. Too late to change what had happened to us.
 
Dad, as always, looked on the bright side. "We can't achieve victory without them, Bertie," he explained. "Britain needs American troops and trucks and tanks. We need them all. Be polite when you encounter anyone from the United States."
 
And so I tried again. "Sorry I knocked you down, miss. I'm a civil defense volunteer. It's my job to tell you to get to the shelter immediately. It's just up the street."
 
The girl snorted as she stood. She brushed off her coat. "You don't look very official. You look like a kid. And was that a tin pan on your head?"
 
I felt my face burn. "I'm thirteen. It's just . . . this is the first time I've been on duty during a raid and I couldn't find--"
 
That was as far as I got. All at once, the night splintered apart. Whoomph. Bam!
 
"Get down!" I hollered. I had just enough time to grab LR and throw myself to the pavement. I curled over her warm, furry body and whispered, "It'll be all right, girl."
 
We were lucky. I felt the ground shake, but the bomb had hit nearby, most likely a block or two away. I glanced up to check on the stranger. What is she even doing out alone at dusk? I wondered. Most people headed inside on a late winter afternoon, especially now that the German bombing raids had begun again.
 
"Please, miss . . . it's not safe to be out."
 
The girl shot to her feet. "I've got to go."
 
And then she was gone, flying off down the street, her dark blue coat flapping against her thin legs. Good, I thought. Maybe the noise has scared her. Maybe she'll follow directions and get to safety.
 
"Go past the big church on your left," I bellowed. "You'll see the sign for the shelter to your right." I couldn't be entirely sure, but it looked as if she'd darted right past it. I shrugged. Well, she wasn't my problem. Time to get to the command post.
 
LR wriggled out of my arms and started sniffing around. I went searching for the tin pan to stick back on my head. Next thing I knew, LR was at my feet, tail spinning like a propeller. Woof! Out came a muffled bark. Her little jaws were clamped onto something. "What have you got, LR? Drop it!"
 
I was about to reach for the object when the sound of footsteps startled me. I turned to see an older couple passing by, heading in the same direction as the girl. "Let's go, dear," the man called to the woman. "Almost there."
 
"I'm a civil defense volunteer," I hollered. "Take shelter now!"
 
"Thanks, lad, but we're almost home," the man said, reaching out to grab his wife's hand. "We've got a Morrison shelter under our kitchen table. We'll be safe."
 
A hatless young man with short dark hair came bounding right behind them. I tried my warning again. "Get to the shelter!"
 
He shot me a frown. I had a quick impression of an angular face and intense, blazing eyes. He looked preoccupied, as if he had something else on his mind besides ack-ack guns. And then, like the other three, he hurried off down Maddox Street.
 
"I give up! No one pays me any attention," I complained to LR, who was still wagging and waiting for me to claim what she'd discovered. I picked up a battered red notebook, small enough to fit in my trouser pocket. I slipped it in without thinking much about it, then reached out for LR.
