Ben. âHas Gran lost her marbles?â she whispered. The car was lurching wildly over the furrowed ground.
âNearly there,â called their grandmother over her shoulder.
Now the children could see a helicopter in the field ahead. A young woman jumped out. She was wearing jeans and a thick jacket and her blonde hair was tied in a rough ponytail.
âThatâs Erika,â said Gran. âSheâll be taking you from here.â She bumped the car to a halt. âHave fun and be safe,â she said, blowing them a quick kiss as they got out. âAnd donât worry about your mum and dad. Iâll deal with them. See you soon.â She hurtled off across the field.
âThis is so unreal!â Zoe muttered as the woman came forwards to shake their hands.
âGood morning, Ben and Zoe.â The woman had a German accent. âIâm Erika Bohn, Dr Fisherâs second-incommand. Iâm here to take you to the Island.â She led the way to the helicopter and settled herself in the pilotâs seat. âStrap yourselves in,â she said. She put on her headset and handed them some ear protectors. She began flicking switches. The door closed and the rotors vroomed into life.
âWhere are we going?â asked Ben, shouting above the noise.
âAny questions will have to wait for Dr Fisher,â Erika told them as they flew north over fields and towns. âHeâs bursting to tell you all about it himself and would never forgive me if I let anything slip.â
Zoe sniffed the air. âWhatâs that smell? Is everything all right with the helicopter?â
Erika chuckled. âI forgot to warn you. We use alternative energy sources at Wild. This helicopter is fuelled by chicken manure.â
âYou mean poo ?â said Ben.
âYes,â said Erika. âItâs environmentally friendly. And free â thereâs plenty on the Island. But it does take a while to get used to the smell.â
Now theyâd left the land behind and were flying over choppy waves.
âLanding in thirty seconds,â Erika announced.
âWhere?â whispered Zoe.
âLook, thereâs a little island ahead,â
Ben told her, looking out of his window.
âThough that canât be it. Itâs too small.â
But Erika was bringing the helicopter down on a bare patch of earth among wild grass and bushes. Ben and Zoe jumped down and gazed at their desolate surroundings. Erika appeared at their side. She pulled a remote control from her jacket and pressed a button. Sheets of old wood suddenly rose from the ground around the helicopter and made a shelter. A corrugated roof slid up from one of the walls and slammed down on top.
âNow no-one will know thereâs a helicopter there,â she explained. âItâs important for Wild to stay absolutely secret. Follow me and mind where you step.â She dodged round a pile of droppings. âThereâs âfuelâ everywhere.â
She led the way through what looked like a chicken farm. There were tatty henhouses and chickens running about freely.
âIt looks a mess,â said Erika, âbut thatâs all part of Wild HQâs disguise. And I promise you the chickens are well looked after.â
âLook at the chicks!â cooed Zoe, stopping to watch a mother hen stalk past, followed by her brood. âTheyâre just like little balls of fluff!â
âGooey overload.â Ben pretended he was being sick.
Zoe stuck out her tongue at him, as Erika flung open the door of a rickety shed. There was an old-fashioned toilet inside. âIn we go!â she said cheerfully. Ben and Zoe exchanged a look. They knew what each other was thinking. This was getting seriously weird.
It was a tight squeeze, especially after Erika had pulled the door shut and drawn the bolt across. She pulled the chain. Instead of the expected noise of water gurgling, there was a
