instantly hit by two things: the hot, bright rays of the sun and the realization that we were now completely exposed to anybody watching the river. I ducked down further into the water to escape both the heat and any eyes that might be trained on the water.
âAre you sure theyâre gone?â
âTheyâre gone . . . for now,â Jack said.
This was crazy. Why were we risking being seen to get some patched-up, old inner tube? Then I realized that it wasnât the tube Jack wanted. It was just an excuse to get a closer look.
There was a slight dip in the creek and we picked up speed as we neared the bridge. I looked up but couldnât see the very top any more. I let go of the tube at almost the same secondas Jack jumped off. He towed the tube behind him as we both swam for the side, the place where the other tube was trapped. The current lessened and the water became shallow. My feet touched bottom and I waded over to the side. I grabbed the inner tube and flipped it over. It had a small red mark by the valve. It was my inner tube.
âHold onto this,â Jack said, pushing his tube toward me.
I grabbed it. Why did he want me to hold his tube? In answer to my unasked question he put one foot on the bottom support of the bridge and heaved himself up and out of the water.
âWhat are you doing?â I demanded.
âI need to see something up close.â
âSee what?â
He didnât answer, but I already knew what he wanted to see. He started up the trestle, climbing from support to support. I wanted to call out, but I didnât. This was crazy! What if he fell, or those men came back or . . . something exploded? Even if the wires werenât attached, they were still explosives!
âPlease come down, Jack!â I hissed as loud as I dared.
He was perched beside one of the dark patches. It looked like a big lump of clay. He reached out a hand toward it!
âJack, donât!â
I looked up at him. Heâd taken some of it and he seemed to be studying it andâ
âUuugggg!â I screamed in shock as something fell down and hit me in the face.
âItâs just clay!â Jack called down. âClay! Here, catch!â
He dropped another chunk, and without even thinking I reached out and grabbed it. I played around with it. Clay. It was clay.
âTheyâre all clay!â
I looked up at Jack. Heâd moved along the supports and was holding more clay in his hand. He let it go, and it dropped into the water with a large splash.
He climbed down the supports, finally slipping into the water and swimming over to my side.
âDo you understand what happened?â I asked.
He shook his head. âNope . . . but Iâm tired of not knowing, so Iâm going to find out.â
CHAPTER FIVE
â JACK, WE SHOULD BE going home.â
âWe will go home. After Iâve got some answers.â
âI just donât think we should be doing this!â
âMake sure you stash your inner tube high enough up on the shore so it doesnât wash away this time.â
He always knew what to say to shut me up. I was sure I wouldnât be hearing the end of that for a long time. I pushed the tube further up the bank, away from the edge of the creek.
âIt would be better if we had our shoes, at least,â I said, trying to throw up some excuses. âCouldnât we come tomorrow and bring shoes?â
âGood idea. Today we wonât have shoes and tomorrow, when we come back, weâll have shoes.â
âI meant we could just come tomorrow!â I explained.
âDo you really think weâll be able to find out everything in this one trip?â
âNo, I guess thereâll be some things that . . . wait, what makes you think Iâm coming back here again?â
âBecause if Iâm coming, then youâre coming,â Jack said. âUnless you want that old lady from up the street to watch
