closed the door, and then I was alone with them in this shadowy, sneezingly dusty cellarâalone with them and the pirate chest.
I peeped around the ancient curtain.
âOkay,â said Gwendoline. âGive me the tools.â
Julius opened his backpack and handed his sister a hammer and a long, slim metal bar. She stuck the metal bar just underneath the lock and started hammering at it as energetically as if the closed chest contained a yearâs supply of gummy bears.
We waited, and waited and waited. I would have fallen asleep, if it hadnât been for the deafening racket she was making.
âWant me to take over?â asked Julius after a while.
âAlmost . . . done . . . ,â she grumbled between her teeth, still banging at the pirate chest and showering it in pretty sparkles of sweat.
âWould have been easier if you hadnât lost the key,â said Julius.
âVery . . . funny,â said Gwendoline. âHavenât. . . lost it . . . someone . . . stole it!â
And finally the lock exploded into splinters of metal and wood, some of which landed dangerously close to my shiny shoes.
âGood job,â said Julius. âLetâs see. Anything missing?â
Gwendoline opened the chest, which groaned as if annoyed to be so rudely awakened (I certainly would have been). They peered into it for a while, moving stuff around.
âNot that I can tell,â murmured Gwendoline. âNo, everything seems to be just as we left it.â
âI told you,â said Julius. âNo one stole that keyâyou mustâve lost it somewhere.â
âI was worried about those kids roamingaround,â said Gwendoline. âYour little friends from Goodall.â
âOh, theyâre completely harmless,â said Julius. âI got one of them talking this morning. She told me they suspected that someone was poisoning the team. So I made up a story about seeing Rob Dawes mixing stuff into their food. That should keep them busy for a while.â
I mentally cursed Gemma so abundantly that her unearringed ears must still have been ringing the next morning, though she probably interpreted it as a foreboding of wedding bells with the devious Julius.
âWell,â said Gwendoline, âuntil I find the key, letâs leave that thing here. We canât hide it anywhere in the boathouse, and we canât leave it outside now that the lock is broken. Letâs get what we need from it immediately and come back for more whenever necessary.â
They crouched down and filled Juliusâs backpack with things I couldnât see. Then they closed the chest again, pushed it against a wall, covered it with old furs and a Persian rug andfinally left the room, helpfully neglecting to turn the lights off.
As soon as theyâd gone, I leaped out of my hiding placeâmy lungs as dusty as if Iâd been vacuuming up the room with my nostrils for the past two hoursâand pushed away all the rags that theyâd dropped on the chest. Gingerly, I opened it.
It was half-full of bags.
Bags of
powder
.
Blue powder, white powder.
âWell, well, well,â I murmured, âwhat can that powder be, then? How about
poison
?â
So I took one, stuck it inside my dress pocket, and put the chest back into place. Then I took some time to congratulate myself.
âWell done, Sesame. This was a good evening. You hadnât planned to go on a mission, but a good supersleuth knows that the unpredictable is always the best ally.â
I shook my own (right) hand with my own (left) hand and merrily prepared to make my way back to the door.
And then the only lightbulb in the cellar burned out with a
ding
!
I didnât panic. Supersleuths donât panic. They embrace the unpredictable. âHurrah!â I said to the darkness around me. âThe lights have gone out. This gives me a
