Robert Dugoni's Tracy Crosswhite Series Keeps Growing in 2026

Robert Dugoni is maintaining a notably ambitious release schedule in 2026, with two new novels arriving across different seasons of the year. According to Shelf Reflection's most anticipated books of 2026 list, Her Cold Justice landed on January 27, 2026, as part of his Keera Duggan legal thriller series, while One Split Second — the twelfth installment in the Tracy Crosswhite series — is slated for September 15, 2026.

Sustaining two active series simultaneously is no small undertaking, and the fact that Dugoni is delivering entries in both within a single calendar year signals a remarkably productive stretch for the bestselling author.

The Tracy Crosswhite series began with My Sister's Grave, a mystery thriller in which a Seattle homicide detective is driven by the disappearance of her sister two decades earlier — a premise that grounded the series in deeply personal stakes from the start.

That emotional foundation has proven durable. As Most Recommended Books notes in its comprehensive series guide, "a big part of the appeal is the way Dugoni lets Tracy's world expand without losing what made it work in the first place" — her colleagues, office politics, and the strain of being a woman navigating a demanding profession all remain central.

The series listing at Fantastic Fiction confirms that One Split Second arrives as the twelfth numbered entry in the Tracy Crosswhite sequence, with a thirteenth installment, Graves Tell Lies, already listed for 2027 — suggesting the franchise shows no sign of decelerating.

According to a new mystery and thriller releases roundup at Jen Ryland's blog, One Split Second sees Tracy tackling two cases separated by 45 years, with a connection described as shocking — a structural choice that fits squarely within the series' history of weaving cold-case intrigue into contemporary investigations.

The September release has already translated into real-world author events. BookTree in Kirkland announced that Dugoni appeared live at the bookstore on October 2, 2026, in support of One Split Second — his twelfth Tracy Crosswhite mystery thriller.

That kind of in-person bookselling presence remains a meaningful signal of an author's relationship with independent retail, a relationship that crime fiction readers and the indie bookshop ecosystem have long sustained together.

For readers newer to Dugoni's work, Most Recommended Books has published a complete ordering guide covering all 39 Robert Dugoni books, updated recently — a useful entry point given the breadth of his catalog across the Tracy Crosswhite and Keera Duggan series.

It is also worth noting that My Sister's Grave, the novel that launched the Crosswhite franchise, has previously been optioned for television series development, according to Dugoni's own official news page — a detail that underscores the commercial and narrative staying power of the original premise at the series' core.

With one 2026 release already on shelves and a second confirmed for the autumn, Dugoni's output this year reflects the kind of sustained series momentum that is increasingly rare in commercial crime fiction, where audiences demand consistency and authors must deliver it without sacrificing quality. My Sister's Grave, the book that started it all, remains a strong entry point for readers considering the Crosswhite world.
