After the old man returned from the mountains, his life quickly returned to its normal rhythm, and with Richelle's careful treatment for a few days, his spirit and complexion had markedly improved.
However, he didn't attend Alexander Lewis's funeral; he only sent the butler.
This move, in fact, was both reasonable and appropriate.
Firstly, he was an elder, advanced in age. It was quite normal for him not to attend.
Secondly, Alexander was killed by a sniper because he had kidnapped Tifanny. In other words, he brought this upon himself and was not deserving of sympathy.
Thirdly, if Alexander hadn't died, Tifanny...
The old man didn't dare to think about the third point.
During those days in the deep mountains, his sleep was disturbed by nightmares about Alexander, that beast, repeatedly haunting his dreams.
Yet, this wholly reasonable and appropriate behavior of the old man deepened Mrs. Lewis's resentment towards him.
