Robert B. Parker's Broken Trust
Spenser investigates the past secrets of an elusive tech billionaire in this latest installment of Robert B. Parker’s beloved series, and the first written by celebrated writer Mike Lupica.
Andrew Crain has it all: a brilliant scientist and astute businessman, his groundbreaking work with lithium has made him one of the world’s richest men. He is universally adored and admired; that is, until Crain’s beautiful wife, Laura, comes to Spenser hoping that he can find out what skeletons lurk in her husband’s closet. Though Crain is a generous philanthropist and loving family man, she is concerned—he has recently become secretive, bordering on paranoid, and prone to violent outbursts. This is the opposite of the man she knew, and not only does his behavior put their marriage at risk, but also a lucrative company merger that would be life-changing for the Crains, their business partner, and everyone associated. Laura wants Spenser to find out what has gotten into her husband, before it’s too late.
As Spenser digs into the billionaire’s past, he realizes that the man may have done terrible things on his rise to the top—but he also may have had good reason to. There are no clear answers here, and quickly enough, what Spenser discovers will cause him to question his own views on morality—and place him in grave danger.

Mike Lupica
For Mike Lupica, storytelling has always been about more than just who wins the game — it's about the grit, the heartbreak, and the small triumphs that happen when no one's looking. Whether chronicling the fierce dreams of young athletes in Travel Team and Heat or stepping into the sharp-edged world of crime fiction with the Robert B. Parker continuations, Lupica writes with a heart that beats just as hard as his characters’.
Growing up in Oneida, New York, and later making his mark in the newsrooms of Boston and New York City, Lupica sharpened his voice as a sports journalist long before he became one of America’s bestselling novelists. His columns for the New York Daily News weren’t just about scores; they captured the spirit of cities, teams, and the people who believed in them. That same pulse of authenticity runs through his fiction, giving even the quietest moments an unmistakable weight.
Spenser
In the layered streets of Boston, where power shifts like the tides and loyalty is the rarest currency, one man has built a career on standing firm when others bend. The Spenser series carves out a world that feels startlingly real—gritty yet sharply human, laced with danger but grounded by heart. At the center of it all is a private investigator whose code of honor is as unshakable as the city’s granite foundations.
Spenser consists of fifty-two primary books, and includes one additional book that complement the series but is not considered mandatory reads and series is set to expand with the upcoming release of one more book. The current recommended reading order for the series is provided below.
