Caleb waited for a few moments before he felt one of his shadows communicate with him through their spiritual connection. The shadows might not be able to talk. But they are connected to him through a spiritual link. After all, they are his shadows. Truly a part of him.
Instinctively, Caleb felt that he could share senses with the three shadows. So he decided to share senses with the first shadow which had reached his father's room and was currently hiding in the shadows of the door.
Just like a CCTV for remote viewing. Caleb could see what his shadow was seeing even though it didn't really have eyes. Hear what it was hearing and so on... At this moment, he saw his father sorting out documents on a study table with a yellow old-fashioned lamp on top of the desk. He has a serious business expression.
'This old fellow is really fond of business, like Delvin.'
