Last First Line?

I know I said I was going to focus on last lines for a bit, but this first line from the novel I'm currently reading caught my eye:

"Dying slowly of bone cancer the old man, shriveled now, sat as ever in his great armchair, tears of lonely pain sliding down crepuscular cheeks."

Not the best first line ever, and doesn't do the intial situation justice as the old man dies in the next few pages and tells his greatest sin to the protagonist who he thinks is his priest. What I like about it? I love the fact that he worked a great word like "crepuscular" in.
