gracefully offshore before diving for small fish in the incoming tide.
Caves on the seashore were something new to Tapser, and he found that they were cold, damp and slippery, not the least like the ones he had read about in books. Somehow he thought they would be dry and warm, like the one Robinson Crusoe had lived in.
âWe know every inch of the caves on our own side of the harbour,â RóisÃn told him as they went from one cave to another, âbut we donât come over here much.â
They were in a fairly big cave now, and Cowlick crouched and shone the torch up into it. âAnother dead end,â he announced.
âBut we must be nearly opposite the Castle Spa by now,â said Rachel.
âWell, that seems to be the last one on this side of the point,â said Cowlick, âand I think itâs time we were getting back.â
âWeâll just have to continue the search in the morning,â said RóisÃn. âIf we canât get around the point weâll try and get down to the rocks on the far side.â
They turned to go.
âWhereâs Prince?â asked Tapser.
They looked around. The collie was nowhere to be seen, and Tapser called him and whistled.
âThere he is,â said Cowlick. âDown by the waterâs edge at the point.â
Prince barked and disappeared again.
âCome on boy,â called Tapser, âweâve got to go.â When Prince didnât come, he made his way over the rocks to see what was keeping him. Moments later he shouted to the others, âI think heâs discovered another cave.â
Cautiously they slithered down the rocks and edged their way around to the point. There they found Prince exploring a large round cave. It was much nearer to the sea than any of the other caves â so much so that the water went in a short distance with each wave and then drained back out.
âI think this is the one weâre looking for,â said RóisÃn.
âLetâs tell Peppi,â Rachel suggested.
âWeâll have to make sure first,â said Tapser.
âAll right, but we must be careful,â warned Cowlick. âWe donât want to be cut off.â
âI donât know,â said Rachel as they made their way into the cave. âI donât think Peppi meant us to go into it, just to find it for him.â
âShush,â said Cowlick, âand keep together.â
They could see by the light of the torch that the cave was deep.
âI still think we should turn back and tell Peppi,â whispered Rachel.
âListen,â said Tapser. âI can hear something. Come on, we canât turn back now.â
Soon they came to a large cavern. Climbing onto a shelf of rock, they saw several tunnels branching off it. One was blocked by an iron gate, and peering through they found themselves looking into the bottling plant at the Castle Spa. White-coated workers were operating the machine, which sparkled and spun as it filled a seemingly endless row of bottles, capped them and placed them into crates.
âThereâs Max,â whispered RóisÃn. âBut I donât see Whaler or Scamp.â
âLetâs see where these other tunnels lead to,â said Tapser. âThey might bring us out on top.â
Tapser held on to Prince, and holding on to each other they crept into one that sloped upwards. Here and there Cowlick stopped to shine his torch around the damp walls.
âWe still seem to be going up all right,â whispered RóisÃn.
âBut where to?â came Rachelâs voice from behind.
âThatâs a good question,â said Cowlick, straining his eyes to peer ahead of them.
âWell, weâve come this far,â said Tapser. âWe might as well keep going.â
Eventually even Tapser had to admit that they were getting nowhere. âMaybe Rachelâs right,â he said. âWeâd better go back
