Spare Change by Robert B. Parker

When a serial murderer dubbed "The Spare Change Killer" by the Boston press surfaces after three decades in hiding, the police immediately seek out the cop, now retired, who headed the original task force: Phil Randall. As a sharp-eyed investigator and a doting parent ("You're smart. You're tough. You, too, are a paradigm of law enforcement perfection, and you're my kid"), Phil calls on his daughter, Sunny, to help catch the criminal who eluded him so many years before.
