CHAPTER NINE
âYou mean the sharkâs a robot?â Thomas exclaimed.
Ben nodded. âIt guards the submarine. Itâs got some kind of movement sensor. It only saw me when I moved.â
âSo you need to get rid of the shark before you can get into the submarine,â Tim said.
Ben gulped. He had not actually thought that far ahead. He thought of the sleek, sinister lines of the submarine and said, âAnd what about the Viperfish? We need to get him out of the submarine too!â
âYeah, then we could throw a net over him, or something,â Tim said.
âThereâs an old net over there on the rocks. We could use that,â Thomas said.
âGood idea!â
âHow are we meant to get him out of the submarine?â Meg wanted to know.
Benâs mind was skipping ahead quickly. âWell, heâs already caught one mermaid, hasnât he? Bet you he wants more. Thatâs why heâs still lurking around here. Why donât we lure him out by making him think he can catch another mermaid?â
âI could dress up in my mermaid outfit and sit and comb my hair on the rocks and sing,â Meg said, looking very pleased at this idea.
âIt sounds too dangerous,â Thomas said. âI donât want him catching Meg too!â
âWeâll have to have some kind of decoy,â Tim said. âI wish we had another mer-boyâs tail.â He could not help being envious of Ben.
âIâll call Delphina,â Sechiel said. âI can swim out holding on to her fin.â
âYouâre still too badly hurt,â Meg said. âYouâll never be able to hold on.â
âWhat about me?â Tim said hopefully. âCouldnât I swim out with her? If you explained I was a friend?â
Sechiel nodded his head reluctantly. âI suppose thatâd be all right.â
âFantastic!â Tim did a dance of joy.
âThat sharkâs awfully fast, Tim,â Ben said. âWe donât want him catching you. I think we need twodecoys, moving back and forth, so the shark gets confused and doesnât know which way to go.â
âI guess thatâd better be me!â Thomas cried.
âWe need you here on the shore to help Meg throw the net over the Viperfish,â Ben said. âItâs heavy â itâll take at least two of you to lift it.â
âYes, we need someone big and strong and hairy!â Thomas flexed his muscles.
âBut what about the second decoy?â Meg asked.
âIâve got an idea for that,â Ben grinned. âGive me your mermaid doll!â
âWhat for?â she demanded.
Ben chuckled. âYou donât really want to know.â
A few minutes later, Meg hobbled out from behind a boulder wearing her mermaid dress. The boys hoisted her up onto Lookout Rock, where she sat with her glittery green tail spread over the stone, combing her short blonde hair and humming out of tune. The others hid and watched.
The submarineâs black watchtower slowly emerged from the sea, water cascading away. Slowly, slowly, it rose, then a trapdoor opened and a man dressed in a black wetsuit clambered out. He stood staring at Lookout Rock, binoculars held to his eyes. Meg tossed her blonde hair and sang a little louder.
âRight, heâs taken the bait.â Ben slid down into the witchâs cauldron. The tide was rising and so it felt rather like being thrust into a washing machine. Frothy water churned all round him and he bobbed up and down, trying not to get knocked against the rock walls. âWish me luck!â
âBe careful!â Tim cried as Ben dived down into the deep, black, churning water of the witchâs cauldron and disappeared.
âIâll call Delphina now.â Sechiel drew a small triton shell out of his seaweed pouch and put it to his lips. He blew and a high, mournful, eerie noise rang out. Again
