Callum had always had a high EQ, so even though Damon had called him out, his expression remained unchanged as he said calmly, "Grandpa, there must be a misunderstanding. We and Tristan have been close friends for years, and almost everyone in LA knows this. How could we have killed him? I bet the Parkers are just using this as an excuse to attack us. Can they produce any evidence?"

He was actually not as calm as he seemed to be on the surface.

The fact that the Parkers had already suspected them meant that it was definitely a huge warning. If they searched along the clues, they would definitely be able to find traces of evidence from their bank transaction records and call history pointing to them.

They had planned this murder too hastily. In fact, Callum had begun devising it immediately after Lucas rejected his friendship and he left Caldo Mountain, which was less than an hour before Tristan's death.
