    S pooksville seldom got really hot. Nestled among the hills beside the ocean, Spooksville was usually cooled by a breeze preventing it from becoming uncomfortable, even in the middle of summer. But in the last half of July, only a couple of weeks after Adam Freeman and his friends got trapped in the Haunted Cave, the temperature rose sharply. At midday the thermometer burst past a hundred degrees. To get away from the heat, Sally Wilcox suggested they head up to the reservoir.
    â€œWe won’t go in the water,” she said. “You don’t want to do that. But it’s always cooler up there.”
    The four of them: Sally, Adam, Watch, and Cindy were seated on Cindy Makey’s porch, drinking sodas and wiping their sweat-soaked foreheads. Adam stared at the half-burnt-down lighthouse—less than a quarter of a mile away—where he had wrestled with a ghost earlier in the summer. He felt as if he were about to catch fire. He couldn’t remember it ever being so hot where he used to live in Kansas City, which was known for its hot summers. He wondered what had brought the heat.
    â€œWhy can’t we go in the water?” Cindy asked.
    â€œBecause you’ll die,” Sally said simply.
    â€œThere are no fish in the reservoir,” Watch added. “So there’s got to be something unhealthy about the water.”
    â€œBut Spooksville gets its water from the reservoir,” Adam said.
    â€œThat’s why so many children in this town are born mutated,” Sally said.
    Cindy smiled. “You were born here, Sally. That explains a lot.”
    â€œNot all mutations are bad,” Sally replied.
    â€œThe water is filtered before we drink it,” Watch said.
    â€œWhat’s filtered out?” Adam asked.
    â€œI don’t know,” Watch said. “But it must betoxic stuff. The filtration plant has a habit of blowing up every couple of years.”
    â€œWhy’s it cooler at the reservoir?” Adam asked.
    Sally spoke. “Because Madeline Templeton—the witch who founded this city two hundred years ago—tortured fifty innocent people to death up there. The horror of that event psychically reverberates to this day, making the whole area cold as ice.”
    Cindy made a face. “And you want to go up there to cool off?”
    Sally shrugged. “There is horror on almost every street in Spooksville, if you look deeply enough into the past. On this exact spot, where your house was built, Madeline Templeton once cut off a kid’s head and fastened it onto a goat.”
    â€œYuck!” Cindy said. “That’s gross.”
    â€œYeah, but the kid was supposed to look like a goat anyway,” Watch said.
    â€œYeah,” Sally agreed. “Maybe the witch did him a favor.”
    â€œI don’t know if she tortured the people at the reservoir to death,” Watch continued. “I heard she just made them go swimming in the water, and their skin turned gray and their hair fell out.”
    â€œI would rather die than lose my beautiful hair,” Sally said, brushing her brunette locks aside.
    â€œI think the area is cooler because of all the subterranean streams,” Watch said, finally answering Adam’s question. “If you put your ear to the ground, you definitely hear gurgling water.”
    Adam wiped away more sweat. “Well, should we go up there?”
    Cindy was doubtful. “The Haunted Cave is up there.”
    â€œThe Haunted Cave can’t hurt you unless you’re stupid enough to go inside it,” Sally said.
    â€œThank you, Sally, for reminding me of my past mistake,” Cindy said.
    Sally spoke sweetly. “Don’t mention it, Cindy.”
    â€œThe Haunted Cave is high above the reservoir,” Watch said. “We can’t ride our bikes up that far, but we can take them as far as the reservoir. We could be there in less than twenty minutes.” He tugged at his T-shirt, trying
