old dinosaur of a computer.â
He ended the transmission and turned to Ben and Zoe. âSorry,â he said, in English. âWe have to return now. Just a little problem with our guest bookings.
Weâll come again tomorrow morning.â He turned and headed back along the walkway towards the reservation.
âWeâll follow in a second,â Ben called after him. âIâve just spotted a broadbill â must get a picture.â He pulled Zoe to a halt. âWe havenât had a chance to play the recording,â he muttered, as he aimed his camera at the bird.
âThen we come back tonight,â said Zoe. âOn our own.â
CHAPTER
FIVE
Zoe crept over the bare wooden floor of their bedroom and nudged her brother through his mosquito net.
âWake up,â she whispered. âWeâve got two hours until sunrise.â
Ben opened his eyes and sat bolt upright in the dark. âLetâs go.â
They dressed quickly and put on their backpacks. Theyâd filled them the night before with water, their first aid kit and BUGs. Having put on their EEL belts and boots, they snatched up their night goggles.
Zoe slowly opened the door.
âShhhh!â hissed Ben as the hinges groaned.
âLucky there are no stairs,â muttered Zoe. âItâs bad enough in this creaky wooden corridor.â
They stepped outside into the silent, shadowy compound. As soon as they put on their goggles the scene was bathed in green light. Deep puddles lay on the ground and they could hear water dripping from the trees.
âLooks like weâve just missed a shower,â whispered Ben.
Zoe turned a dial on the nosepiece to adjust the focus. âWeâll follow the satellite map on the BUGs.â
They crept for the cover of the trees.
âThe black zigzag lines are the walkways,â said Ben, studying the image on his BUG screen. âAnd thereâs Kawanâs territory, where the walkways come to the river.â
âThere must be a more direct path than that,â replied Zoe.
Ben pressed a button and a different map appeared, showing a narrow track that went right to the south-east edge of the reservation. âThisâll take us there.â
âTuck your trousers into your boots,â Zoe reminded him. âThereâll be snakes.â
âAnd arthropods and invertebrates,â said Ben eagerly.
âCreepy-crawlies in other words.â Zoe grimaced.
âWatch out for the ten-centimetre-long cockroaches!â Ben teased, but Zoe refused to rise to the bait.
âScent dispersers on, too,â she said. âThat will help keep unwanted guests away.â
The rough path led between huge, thick tree trunks deep into the darkness of the rainforest. The children moved along as quietly as they could, listening intently to the sounds around them.
Suddenly there was a loud whoo-aa call and a long, skinny shape swung down in front of them. It peered at them intently from under a pair of thick eyebrows. The children stopped dead, hearts beating fast. Then the creature gave a cry and shot back up into the trees.
âIt was a gibbon!â whispered Zoe, checking the analysis on her BUG. âWonder what it made of our goggled faces!â
âWhatâs that?â gasped Ben, pointing into the darkness. âAround that trunk. It looks like a huge snake!â
âItâs not moving.â Zoe laughed. âItâs just a root thatâs twisted round the tree.â
They pushed their way through a bank of thick fern leaves that hung across the path.
âI can hear the river,â said Ben. âWe must nearly be in Kawanâs territory. The walkways ought to be above us now.â
âThereâs a sign on that trunk,â said Zoe pointing. âPlatform Twenty-two â thatâs where we were earlier. Weâve arrived.â
Something moved low on the ground ahead. Through their goggles they
