Who Takes Over When a Crime Series Changes Authors?

After an author retires, passes away, or stops writing a series, usually the series is over. But sometimes it isn’t. Sometimes we see new books in the series with the author’s name prominently on the cover. Then we know the series has been picked up by another writer.

But what doesn’t it mean exactly? Did the new author pick up an unfinished manuscript and completed it? Did they start writing a new book from scratch? And why don’t the covers always show who is writing the series currently?

And how does this affect your reading of a series? How do you know where to start, which book comes next in the actual chronology?

Why Is the Original Author’s Name Still on the Book Cover?

Robert Ludlum died in 2001, but his name is still listed on the Bourne book covers. Even for books like Robert Ludlum’s The Bourne Evolution, Robert Ludlum is the original creator of Bourne, and Brian Freeman wrote the actual book.

Jack Reacher is a less obvious example because both writers were alive when Andrew Child took over the series.

Lee Child planned to hand over the series to his younger brother Andrew Grant with The Sentinel in 2020. The four books from The Sentinel through The Secret are part of this transition period. Andrew Grant, who now writes the series as Andrew Child, took over with In Too Deep in 2024, but the books still have both names on the cover. The brothers talk about that handover and the byline in this interview with CrimeReads.

From the cover alone, it’s easy to believe that both brothers are still co-writing the books, but as we saw above, it’s not always true.

Caroline and Charles Todd used to write the Inspector Ian Rutledge and Bess Crawford mysteries together under the name Charles Todd. After Caroline’s death, Charles continued the books using his own name. Since the name Charles Todd remained the same on the cover after Charles Todd himself continued writing the books solo, the date of publication alone doesn’t tell you which was the first book he wrote alone.

P. J. Tracy was the pen name of Patricia and Traci Lambrecht. After Patricia’s death, Traci kept writing the Monkeewrench books alone, but the name P. J. Tracy is still on the covers.

Did the New Writer Finish One Book, or Did They Take Over the Whole Series?

Elizabeth Peters was working on The Painted Queen when she passed away, so she never got to finish the manuscript. It was picked up and finished by Joan Hess, and the book was published under both names in 2017. Joan Hess never wrote another Amelia Peabody book after that. Her involvement was just that, one single book.

The Stone Barrington series, however was different. Stuart Woods was working on Near Miss before he died, and Brett Battles finished it, and then he continued the series on his own. Smolder was the first Stone Barrington novel written entirely by Brett Battles.

Albert Campion went through this kind of change twice. Margery Allingham’s husband, Philip Youngman Carter, completed her unfinished Cargo of Eagles and then wrote new Campion books. After several decades, Mike Ripley took an unfinished Carter manuscript left behind by Philip Youngman Carter and wrote Mr Campion’s Farewell, published in 2014, which then he followed with additional Campion books.

How Much Material Did the Original Writer Leave Behind?

An “unfinished book” can have different meanings, depending on the series. When a new writer continues a series, they might get finished chapters and an outline, or they might have only the research files and some plot ideas, which leaves them with most of the writing to do.

When Ryan Steck continued the Alex Hawke series with Monarch, he used Ted Bell’s plot outline and his notes. So Ted Bell left behind some material that could be used to continue the series, but it’s still not clear just how much of the novel Ted Bell had actually written back then.

Bulldog Drummond is yet another example where we have to be careful with the wording. Gerard Fairlie based Bulldog Drummond on Dartmoor on a plot he and H.C. McNeile had discussed before McNeile’s death. Fairlie then continued the series with new stories of his own. So we know McNeile had discussed the plot with Fairlie, but there is no evidence here that he had actually written the book.

From these details, we don’t really know how much of a book was written by which author. Even surviving chapters might have been reworked. However, they help distinguish a book that includes the original author’s writing from a book that was developed based on their ideas. In such cases, the honest answer is that we simply don’t know how much material was left.

Who Decides Who Gets to Continue a Famous Series?

Sometimes the original author chooses a new author. Lee Child began the Reacher handover while he was still involved with the books, and M.C. Beaton chose R.W. Green while her health was failing. Beaton and Green were longtime friends. Her official site describes how she offered him the opportunity to continue Agatha Raisin and Hamish Macbeth. The later books keep both names on the cover.

Felix Francis’s case is quite different. Dick Francis retired from writing, and five years later, when the books were going out of print, his publisher wanted to commission further books to an established writer. Felix asked if he could try first, since he had already worked together with his father previous on some books. The result was Under Orders, published in 2006. They decided to keep the name Dick Francis on the cover since people knew the author so well. Since people loved the new book, Felix continued to write the series. He tells the story in this publisher interview.

Sometimes series are continued after the author’s death. Sophie Hannah was approved by the Agatha Christie Estate to write a new Hercule Poirot book, The Monogram Murders, which was published in 2014. She then continued writing more Poirot mysteries.

So a publisher or an estate can commission only one book or further books in the series. “Authorized” only tells us that the project is approved, but not necessarily who the next writer will be.

What Happens When There Isn’t Just One Successor?

Sometimes a series can have several writers. Robert Ludlum created Jason Bourne, Eric Van Lustbader continued the series, and Brian Freeman later pick up the series from him.

It gets even more complicated when several of an author’s series are continued by other writers. Robert B. Parker’s Spenser, Jesse Stone and Sunny Randall books were continued by different writers, and things changed even more over time. In fact, Parker himself was an author who continued someone else’s story. He completed Raymond Chandler’s unfinished Poodle Springs and then wrote another Philip Marlowe novel, Perchance to Dream.

Tom Clancy was the point in my own research where the apparently simple question “Who took over?” was really the wrong question.

At first I thought I was tracing one succession. Then I had to separate the main Jack Ryan books from Jack Ryan Jr., since the two series had different writers. And then, some writers were continuing the next books, while others were commissioned for one particular title. A writer could even appear in one Clancy series and later turn up in the other.

Every time the answer started looking tidy, another series made the tidy answer wrong.

Eventually I had to ask which Clancy series I was looking at, and who was writing that series at that point.

Will the Character Still Feel the Same?

A familiar character can sound different in another writer’s book. No two people write the same, and even when keeping the same character’s job and history, the dialogue and humor will feel different, and readers will notice.

In an interview with The Big Thrill, Brett Battles describes trying to capture Stuart Woods’s humor, which is very different from his own. He also has to keep track of the characters’ existing backgrounds, so that at times meant that he had to change what he would normally write because it would contradict an earlier book.

Where Do the New Stories Fit?

A new writer who picked up a series doesn’t have to continue exactly from where the previous book left off. The Inspector Frost prequels go back to earlier points in Jack Frost’s career, before R.D. Wingfield’s original novels.

Nick Harkaway’s Karla’s Choice is placed between two existing books in the story’s chronology. The John le Carré Estate places it between The Spy Who Came in from the Cold and Tinker Tailor Soldier Spy, even though it was published much later than the two books.

The Painted Queen does something similar with Amelia Peabody. It was the last novel published, but its story takes place in 1912, earlier than some of Peters’s own books. So it was the last in publication order, but not the last in chronological order.

And sometimes a series returns through the original character’s younger generation. John Creasey’s son Richard went back to the Dr. Palfrey and Z5 world with stories about Thomas Palfrey, the original protagonist’s grandson. So we can read about the family but the story follows a different main character.

When the Famous Author Name Continues but the Series Doesn’t

A new book can still have a deceased author’s name on the cover, even when it has nothing to do with a given series.

Michael Palmer’s third Lou Welcome novel, Resistant, which he had written before he passed away, was published posthumously in 2014 . Daniel Palmer, his son, did not work on it or take over the Lou Welcome series afterward.

Instead, he got involved with a different project. Michael Palmer had been developing the premise for another medical thriller, and Daniel took that idea and wrote Trauma. In his account of writing the book, Daniel explains the conversations they had before his father’s death. He later wrote Mercy and The First Family, also published with the Palmer names, but they are solo Daniel novels.

These books simply continued the legacy of Michael Palmer’s medical thrillers, but they were not part of the Lou Welcome series, so if you’ve read Resistant, you should not expect the same doctor in Trauma.

Sidney Sheldon’s later books show both possibilities. Tilly Bagshawe wrote Mistress of the Game as a sequel to Master of the Game, and Chasing Tomorrow returns to Tracy Whitney from If Tomorrow Comes. However, Tilly Bagshawe also wrote other thrillers that are not part of these series but are still under the Sidney Sheldon name.

With Bagshawe, even identifying the later writer isn’t enough to establish the connection. You still need to know which characters that particular book returns to, if any.

Does a New Writer Change the Reading Order?

Usually, it doesn’t. If another author simply continues the series, the next book remains the next book.

The complication comes when the new writer changes the series. Brian Freeman’s books are a good example. He described The Bourne Evolution as a reboot, bringing Bourne to a modern setting. He didn’t continue directly from the ending of the previous book. In his interview with The Real Book Spy, Brian Freeman explains that he wrote it as a standalone new beginning. This means that someone who hasn’t read the Bourne books before can simply start here, treating it as a new beginning.

With prequels, the question is different. A later writer can write a prequel, but that doesn’t mean we have to read the prequel first, unless there is a good reason for it. Normally, reading the books in publication order is still the best way to start a series.

Where Can You Check Who Wrote a Book?

The acknowledgements or an author’s note are good places to start. A later writer may explain what happened in an interview, and an estate announcement can mention who approved it. Publisher pages also help with credits and where the book fits in the series, but a deceased author’s name may still appear as the main author even when a new writer wrote the book.

For individual series, the Crime Series Handovers Index brings together the original authors, later writers and confirmed handover timelines.

Mystery Sequels is independent of the authors, estates and publishers discussed.
