Ultimately, Spenser must hire a Chicago hitman to help him free the girl from a sociopathic ex lover.

Ten years ago, Paul Giacomin's corrupt father and loose mother used the boys as a pawn in their violent race: Only Spenser could call them off and straighten out the misled teen - almost getting killed in the process. Paul is now 24 and reconciled to his mother's wanton ways. But when Patty Giacomin vanishes, Paul begs Spenser to help him rescue her from the clutches of her boyfriend, a shady character he's sure coerced his mother into running.

Boston's premier P.I. investigates the murder of a prominent local banker with family ties to the Mayflower - and perhaps the mob. It's hard not to imagine the victim's young bride as the one with her finger on the trigger. Even her lawyer thinks she's guilty. But Mary Smith is entitled to the best defense she can afford - and thanks to her late husband's millions, she can afford plenty - so Spenser hires on to investigate.

Heidi Bradshaw is wealthy, beautiful, and well-connected - and she needs Spenser's help. In a most unlikely request, Heidi, a notorious golddigger recently separated from her latest husband, recruits the Boston P.I. to accompany her to her private island, Tashtego, for her daughter's wedding.

Now he is forced to make connections: to the medical technology that will ensure his physical recovery, and to reinforce the tenuous emotional ties he has to those around him.

Connie Kelly thought she'd found her perfect man on an online dating site. He was silver-haired and handsome, with a mysterious background working for the CIA. She fell so hard for M. Brooks Welles that she wrote him a check for almost 300,000 dollars, hoping for a big return on her investment. But within weeks, both Welles and her money are gone.

Gabby Leggett left her Boston family with big dreams of making it big as a model/actress in Hollywood. Two years later, she disappears from her apartment. Her family, former boyfriend, friends - and the police - have no idea where she is and no leads. Leggett's mother hires Spenser to find her, with help of his former apprentice, Zebulon Sixkill, now an LA private eye. Spenser barely has time to unpack before the trail leads to a powerful movie studio boss, the Armenian mob, and a shadowy empowerment group some say might be a dangerous cult.

Jesse Stone, still reeling from the murder of his fiancée by crazed assassin Mr. Peepers, must keep his emotions in check long enough to get through the wedding day of his loyal protégé, Suitcase Simpson. The morning of the wedding, Jesse learns that a gala 75th birthday party is to be held for folk singer Terry Jester. Jester, once the equal of Bob Dylan, has spent the last 40 years in seclusion after the mysterious disappearance of the master recording tape of his magnum opus, The Hangman's Sonnet.

All is quiet in Paradise, except for a spate of innocuous vandalism. Good thing, too, because Jesse Stone is preoccupied with the women in his life, both past and present. As his ex-wife, Jenn, is about to marry a Dallas real-estate tycoon, Jesse isn't too sure his relationship with former FBI agent Diana Evans is built to last. But those concerns get put on the back burner when a major Boston crime boss is brutally murdered. Despite all evidence to the contrary, Jesse suspects it's the work of Mr. Peepers.

Ten years ago, Spenser helped a teenage girl named Mattie Sullivan find her mother's killer and take down an infamous Southie crime boss. Now Mattie - a college student with a side job working for the tough but tender private eye - dreams of being an investigator herself. Her first big case involves a 15-year-old girl assaulted by a much older man at one of Boston's most prestigious private clubs. The girl, Chloe Turner, only wants the safe return of her laptop and backpack. But like her mentor and boss, Mattie has a knack for asking the right questions of the wrong people.

The local cops haven't seen anything like this, but Jesse's L.A. past has made him all too familiar with floaters. This girl hadn't committed suicide; she hadn't been drowned; she'd been shot and dumped, discarded like trash. Before long it becomes clear that she had a taste for the wild life; and her own parents can't be bothered to report her missing, or even admit that she once was a child of theirs. All Jesse has to go on is a young man's school ring on a gold chain, and a hunch or two.

Jesse Stone is back on the job after a stint in rehab, and the road to recovery is immediately made bumpy by a series of disturbing and apparently racially motivated crimes, beginning with the murder of an African American woman. Then, Jesse's own deputy Alisha - the first black woman hired by the Paradise police force - becomes the target of a sophisticated frame-up. As he and his team work tirelessly to unravel the truth, he has to wonder if this is just one part of an even grander plot, one with an endgame more destructive than any of them can imagine. 

When Sunny's long-time gangster associate Tony Marcus comes to her for help, Sunny is surprised - after all, she double crossed him on a recent deal, and their relationship is on shakier ground than ever. But the way Tony figures it, Sunny owes him, and Sunny's willing to consider his case if it will clear the slate. Tony's trusted girlfriend and business partner has vanished, appears to have left in a hurry, and he has no idea why. He just wants to talk to her, he says, but first he needs Sunny to track her down. 

When a popular high school cheerleader dies of a suspected heroin overdose, it becomes clear that the opioid epidemic has spread even to the idyllic town of Paradise. It will be up to police chief Jesse Stone to unravel the supply chain and unmask the criminals behind it, and the investigation has a clear epicenter: Paradise High School.

PI Sunny Randall has often relied on the help of her best friend Spike in times of need. When Spike's restaurant is taken over under a predatory loan agreement, Sunny has a chance to return the favor. She begins digging into the life of the hedge fund manager who screwed Spike over - surely a guy that smarmy has a skeleton or two in his closet - and soon finds this new enemy may have the backing of even badder criminals.
