After a year I’m back to reading the last eight Parker novels by Richard Stark (really Donald E. Westlake). Of all the first lines, the opening of Firebreak (2001) is one of the best:
When the phone rang, Parker was in the garage, killing a man.
There’s this great exchange at the end of the first section:
“I’m really sorry,” Lloyd said. “Some habits just die hard.”
“Some things die easier,” Parker told him.
