"Why are we leaving just like that?" asked Callum once he started driving.
Guang Ying thought for a moment before he asked, "What did you notice in her house?"
Callum hesitated for a moment before saying, "Lots of picture frames, but oddly enough, the pictures in those picture frames were not theirs. At least, I'm pretty sure that one of the people in those photos was Albert Einstein."
Guang Ying nodded.
When he did not say anything, Callum continued, "There's something wrong with that house. When I walked in, one part of the wooden floor felt loose and there was a soft hollow thud. It could be a hidden compartment. She's hiding something."
