Finally, my fingers found what they were looking for and an overhead light snapped on.
"Darby!" Cal shouted as he closed and locked the door behind us.
I squeezed his hand, a warning that we shouldn't go into this blindly because I doubted he had puzzled out all the details as quickly as I had.
"Darby!" he called again and dragged me along with him farther into the living room.
"Wait. Cal, listen to - "
He held up a hand for me to shut up while he stopped next to the piano and peered around a wall to the hallway.
"I think she's down there," he whispered. "Do you hear that?"
I couldn't hear a thing over my booming heart, but I leaned in real close so he could hear me. "I think there might be someone else here."
Even though it could just be Darby, it was still a definite possibility.
