Why couldn't he find anything

Scarlet walked in frustrated. She slumped down into the sofa and sank in.

"Why couldn't he find anything?" she mumbled out loud, in frustration. Ray was the best known investigator of them all. He was good at his job. He was good at finding out hidden truths that no one could comprehend. But then, why couldn't he find the woman? Why couldn't he find the woman behind Ethan's recent change of behavior? Why? Or, could it be that the woman is influencial? Could it be that the woman had connections? Or maybe, Ethan hid her identity? Maybe, he didn't want anyone to know about his intimate relationship? As these thoughts ran through her mind, Scarlet frustratedly threw her phone to the sofa, as she said, angrily, "But I'm his sister! He shouldn't keep this from me!" She let herself slide down the sofa and immersed herself in her own thoughts.
