long word at the time, and didnât notice.â
His mother smiled, but the worried look remained. âThe thing is,â she said, âIâve just been asked if I can go to a conference in Singapore. Itâs very last minute â Iâd be replacing a colleague whoâs ill, and Iâd be away for nearly ten days. And Iâd have to fly out tomorrow afternoon.â
She looked at him anxiously. âWould that be all right?â
âOf course it would.â
âCan you and Dad manage?â
âOf course we can. I mean, weâll
miss
you, butââ
âWill you eat proper healthy meals and not just pick at whateverâs in the fridge?â
âYes.â
âAnd change your clothes sometimes?â
âYes.â
âAnd go to bed at a reasonable time?â
âYes.â
âAnd if you go out during the day, will you stick with friends and leave notes for Dad so he knows where you are?â
âYes.â
âBecause if you only
tell
him things, he forgets. You have to write it down.â
âI know.â
She bit her lip, undecided.
âDonât worry, Mum,â said Stuart. âWeâll be absolutely
fine
.â
THE NEXT MORNING he got to the museum early and was walking in small, impatient circles outside the main entrance when the caretaker turned up at ten past nine, shortly followed by the curator.
âDonât forget your official identification,â said Rod Felton, and Stuart pinned on his hideous MINI EXPERT badge and then made his way to the side room. Sunlight was streaming through the window.
âCan you finish those descriptions by midday?â asked Rod Felton, popping his head round the door. âThen we can print them up and laminate them, ready for the exhibition opening tomorrow.â
Stuart nodded, sure that April would remember a notebook and pen. He checked his watch and frowned. How could she be late when there was so much to do?
He waited another five minutes. Still no April.
He got the little six-spoked wheel out of his pocket and studied it intently from every angle, but there was nothing new to see.
He trudged along to Rod Feltonâs office and borrowed some scrap paper and a pencil and â as an afterthought â a tape measure.
He wrote
THE PHARAOHâS PYRAMID
in large careful letters at the top of the page, and then underlined it. Twice. And then checked his watch yet again.
It was ten oâclock.
April was three-quarters of an hour late. Sheâd said,
Donât touch anything till I get there
, but if he didnât, then he wouldnât be able to describe the tricks properly, and heâd miss Rod Feltonâs deadline. And besides, they were
his
tricks, even if he couldnât actually prove it to anyone. So of course he could touch them if he wanted to.
âRight then,â he said out loud, secretly feeling rather pleased. âIâll just have to start on my own â¦â
He had to write âaboutâ because (as usual) he was too short to measure it properly.
He stood on tiptoe, gripped the nearest snake-shaped handle and pulled. The whole triangular side immediately swung down, cracking him on the head; it was hinged at the bottom, he realized, and was heavier than it looked. He lowered the side to the floor, and stood rubbing his skull for a moment, and then he stooped to get a clearer view of the inside of the pyramid.
It was jet black, so shiny that the varnish still looked wet, and the walls were painted with a scattering of red stars. Stuart took the metal star out of his pocket and held it against one of the painted ones. It was exactly the same size and shape.
He put the star back in his pocket and walked round the pyramid again. However hard he tugged at the handles on the other three sides, none of them would shift.
He lifted the first side up again, and it clicked neatly into position, the pyramid complete once
