about something dangerous living down in the tunnels. Seabrook led a team of scientists down there to investigate but they all vanished. None of them was ever seen again. The tunnels were blocked off after that.â Mr Bill nodded solemnly as we all stared at the picture.
Well, I pretended to stare. Instead, out of the corner of my eye, I was watching the end of the hallway. Was it Mr Slender? Was he trailing us?
âNow, I can see Iâve bored you for long enough,â said Mr Bill with a little smile. He shuffled around another corner. His voice echoed back faintly. âThis way! Come along!â
âHurry up,â said Sophie, when I didnât move.
Reluctantly, I followed them around the corner. The corridor ended in a small, square room with a solitary desk in front of a window and large doors on the left-hand side. I peered around the doors and glimpsed the edge of a bed.
âThis is Nurse Nellieâs office. My office is over here,â said Mr Bill. He limped toward a small door in the opposite wall that I hadnât noticed. âI will leave you in Nurse Nellieâs capable hands. Sheâll sign you into sick bay. Wait there until the bell goes for your next class. And try to avoid Mr Slender for the rest of the day. Tally-ho!â
With a small wave, he turned and vanished through the door into his office.

âJust pop your name here.â Nurse Nellie pushed an open ledger across her desk toward me.
I scribbled my name in the first space and Sophie jotted hers down underneath it.
âHave either of you been to sick bay before?â asked Nurse Nellie.
âUm, no,â I said, wondering how we could escape without making Nurse Nellie suspicious. We had to get out of there and find Michael. Sure, I didnât always like my brother, but I didnât want anything really bad to happen to him either.
Nurse Nellie led us into sick bay, which turned out to be a huge room lined on either side with hospital beds. I guessed when kids got sick at school, it all happened at once.
âThis used to be a ward in the old hospital,â Nurse Nellie explained. She handed me a box of bandages. âReroll them as neatly as you can. Sophie, you can clean the bedrails.â
Nurse Nellie gave Sophie a cloth then bustled to the other end of the room. She disappeared through another doorway,reappearing almost instantly with a large bottle of blue medicine. She unscrewed the lid and pulled out a small tin from the pocket of her starched uniform. âIâve always found adding a little sugar to the medicine makes it much easier to swallow,â she said, tipping some white powder from the tin into the blue liquid.
While she was distracted, Sophie turned to me and whispered, âHow are we going to get out of here?â
I thought fast. If Nurse Nellie was anything like Mum, all we had to do was âaccidentallyâ mess things up. She wouldnât want our help for long after that.
âWatch me,â I said softly. Working quickly, I unrolled the bandages and then bunched them into rough piles. âNurse Nellie? Is this how you do it?â
Nurse Nellie glanced over. âNoooo! Oh, dear! More neatly . Oh, donât worry, I . . . Iâll finish!â
âBut I really want to help!â I told her, fiddling with the bandages so they looked even worse.
âStop!â Nurse Nellie put the bottle of medicine down and rushed over, looking panicky. She took the box of bandages from my hands. âPerhaps you can, er . . . help Sophie?â
âGreat! This is such hard work!â Sophie was sprawled across the head of the bed, rubbing the frame. The sheets were scrunched up around her feet.
âYour dirty shoes!â cried Nurse Nellie. âNow Iâll have to change the sheets!â
âOh, sorry,â said Sophie. She slid her feet off the bed, leaving a pair of long black marks on the white fabric.
âYou know, Nurse Nellie,
