CHAPTER FIFTEEN

"What? What is it?" Brittany was up and out of bed in ten seconds. She ran to her friend. Then she, too, screamed.

Callie was standing on the staircase below, a long knife in her hand. She grinned up at Brittany and Melissa.

"MOM! DAD!" Melissa screamed. Callie looked up at her with a smile.

"They're gone," Callie said simply, heading up the staircase.

"Huh?" Melissa asked, starting to back up. Too late. Callie was now standing in front of the two girls. Wait a minute. Two? Melissa looked around. No. Not two girls. One. Where was Brittany?

"Brittany!" Melissa shrieked, looking around. She glared at Callie. "You killed her. You killed her!"

"No," Callie told her. "Not yet. She hid. She hid from me."

"Duh," Melissa grumbled. "Where are Mom and Dad, Callie? Where are they?"

"I killed them," Callie said, grinning. "I didn't want any witnesses. Not for you. Not for anybody."

"I don't understand!" Melissa wailed, breaking down in tears.

"Look," Callie said, "I don't have time for this. I-I-"Suddenly, Callie dropped to her knees and gasped. The knife fell from her hand. Melissa looked down at Callie, who was lying facedown.

"Melissa-are you okay?" Brittany asked, running up to her.

"I'm fine," Melissa told her. "But Callie..." She gestured to her sister. Brittany looked at Melissa. "I'm so sorry."

"I am, too," Melissa admitted.

"You are? Why?"

"I'm an orphan now. She killed Mom and Dad, and I asked what this was all about and then she got knocked out because-"

"Of me," A voice said. Melissa turned to see May, staring at Callie.

"May!" Brittany shrieked. "What are you doing here?"

May didn't answer. Instead, she gripped the frying pan in her hand and aimed it at Brittany. She missed.

"May, what are you doing?" Brittany asked, standing up.

"I saw everything," May told her. "You were suspecting the wrong person the entire time."

"We-we what?" Brittany asked. May swiped the pan at her again. Brittany easily dodged it.

Melissa stared at May. Was May right? Had the girls suspected the wrong person?

What had really happened?
