There was nothing to see, except the sea. The bed rode too low in the water. Even standing up, Arthur’s view was blocked by the next wave. What he could see was much closer and immediately obvious.
The bed was sinking. Even in this calmer ocean, the mattress was now totally submerged, losing its buoyancy as it absorbed more and more water, the steel frame dragging it down.
It wasn’t going to sink in the next five minutes, but it was going to sink.
Arthur sighed and sat back down, water splashing almost up to his waist. He looked at the cast on his leg and wondered if he should take it off. It was very lightweight and it hadn’t dragged him down before, but that had been a truly panic-driven swim and it would be hard to swim any real distance with it on. But if he took it off, his leg might snap apart again or hurt so much that he couldn’t swim anyway.
He decided to leave the cast on and got out the Captain’s disc again. This time he just held it in his hand and tried to visualise the ship with the glowing green sails coming back to pick him up.
He hoped that was a good thing to visualise. At the back of his mind was a nagging worry that Leaf hadn’t been actually rescued but had gone from one trouble to another. What would the Denizens do to her? They would have been after him, not her. He hoped that since Lady Wednesday had sent him an invitation instead of an attack squad, she might be at least kind of friendly. But maybe that was just a sneaky plan to get him where she wanted. In which case, Drowned Wednesday might take out her bad feelings on Leaf . . .
If Leaf survived that line of lightning, Arthur thought guiltily. Surely that ship would have had some protection …
The bed gurgled under his feet and sank a bit more, reminding Arthur of his immediate problem.
‘A ship!’ he called out. ‘I need a ship! Or a boat! A better raft! Anything!’
His voice sounded alone and empty, lost amid the waves. He was answered only by the sloshing of the sea under, through, and around the mattress.
‘Land would do,’ said Arthur. He said this directly to the Captain’s disc, but once again it didn’t appear to do anything. It was just a carving of a boat on a piece of whalebone.
No land came in sight. Though he still couldn’t see any sun, it got warmer, and then positively hot. Even the seawater now constantly washing over Arthur didn’t cool him down. It was tepid and very salty, as he found when he tasted some on the end of his finger. He was getting very thirsty, and had started to remember all kinds of terrible stories about people dying of thirst at sea. Or going crazy from thirst first and hurling themselves into the water or attacking their friends and trying to drink their blood. . .
Arthur shook his head several times. It looked like he was already starting to go crazy, thinking of stuff like that. Particularly since he knew he couldn’t die of thirst in the House. He might feel like he was, and of course he could still go crazy. . .
Better to think of something positive to do. Like send a signal, or catch a fish. If there were any fish in this strange sea within the House. Of course, if there were fish, there might also be sharks. A shark would have no trouble pulling him off the bed. It hardly qualified as a raft anymore, it had sunk down so far.
Arthur shook his head again to try and clear away the negative thoughts.
Stop thinking about sharks! he told himself.
Just at that moment, he saw something in the water not far away. A dark, mostly submerged shape. A shadow largely under the surface.
Arthur yelped and tried to stand up against the headboard, hopping as his immobilised leg got caught under a fold of sheet. This violent action changed the balance of the bed, and one corner went down several feet, releasing a huge air bubble.
This downward progress halted for a few seconds as air bubbles continued to pop to the surface, then the bed sank like the Titanic, one end briefly sticking straight up before it subsided beneath the waves. Arthur let go of it just in time and pushed himself away. He thrashed out a rough backstroke for a few yards to make sure he wouldn’t be sucked down, then trod water with one leg and his arms circling, as he frantically looked around for the dark shadow again.
There it was, only a few yards away! Arthur braced himself for the shock of a shark’s attack, his body rigid. His head sank under the water as he stopped moving, then broke free again as he instinctively struggled to swim again.
The dark shape didn’t attack. It didn’t even move. Arthur stared at it and saw that it wasn’t a shark. He swam closer to confirm that it was, in fact, a dark green ball about six feet in diameter. It had an irregular surface rather like matted weeds and was floating quite deep, so that only a curve fourteen inches or so high rode above the sea.
