Readers Guide to Nightshade

05.14.2025 by Jen Ryland // 9 Comments

I’m a Michael Connelly super-fan pleased to bring you this Readers Guide to Nightshade. Is Nightshade a series or a standalone? Is it connected to other books in the Boschverse? I’m here to share what I found and am counting on fellow fans to help me puzzle it all out. I’m excited to discuss Nightshade with you!

Jen’s Quick Take on Nightshade by Michael Connelly

Original photo of Nightshade on a blue bookcase with other bright colored thrillers and a J mug
  • To me, Nightshade feels like a standalone novel (I’ll discuss why below)
  • It has familiar Bosch tropes: a LA County police detective is sidelined to Catalina island after a beef with a colleague over a case.
  • There’s a hint of Slough House from Slow Horses to the Catalina Island location, which main character Stilman once calls the “Island of Misfit Toys.”
  • Stilman has a bit of Bosch’s outsider perspective, disdain for authority, and hint of mysticism. Stilman believes the investigator and the victim have a sacred bond.
  • Like most later Bosch books, Nightshade had two concurrent investigations
  • I enjoyed it!
  • Publication date: May 20 2025 by Little Brown. Thanks so much to the publisher for the advance review copy.

Spoiler Free Thoughts on Nightshade

Overall, I enjoyed Nightshade.

That said, it’s hard to get to know a new main character, and some people might find Stilwell a little … dry? He’s a stickler for following the case where it leads, doesn’t care about authority, and wants to do right by the victims. So he feels a little Bosch-like.

Hopefully this isn’t my “new dog” theory I had about Richard Osman’s new book.

But hey, an author is allowed to mix it up a bit. And Connelly has a new Mickey Haller book, The Proving Ground.

Is Nightshade a Standalone or the first book in a series?

I have two reasons to think that Nightshade is a standalone, not the first book in a series. And one reason I could be wrong. (Edited in 2026: I was wrong!!)

Post on Orion books calling Nightshade a standalone thriller

First, this Instagram post by Orion books, who must be Connelly’s European publisher, calls Nightshade a “standalone thriller” and was reposted by Connelly’s official account.

Second, Nightshade takes place on Catalina Island, off the coast of Southern California.

  • Population: about 4000
  • Murders per year: usually none

This makes it a great place to exile Stilwell from his LA County job, but can he solve crime here forever? (Edited in 2026: apparently YES.)


Are There Connections Between Nightshade and other Connelly Books in the Boschverse?

I only found one!

Since this book takes place on Catalina Island, I remembered one connection: Terry McCaleb.

  • He was the FBI agent who worked on The Poet case.
  • McCaleb retired from the police force after a heart transplant, but (plot twist) learned that his heart donor had been murdered, and was hired by her sister to solve the case.
  • Then he married the sister, Graciela, and moved to Catalina Island. But this was back in the early 2000s, as Connelly has Bosch and his characters age in real time. McCaleb died in 2004 after a mixup with his heart medication. Was it murder or accidental? If you remember, please tell me in the comments.

I did not notice any crossover characters or mentions of Terry or Graciela, but if you did, tell me in comments.

The One Crossover I Found

What I did find: a mention of an event in The Waiting, Connelly’s 2024 book with Renee Ballard.

Ballard is assigned to the Open/Unsolved unit. This IS a spoiler for The Waiting, so I’m putting the rest of the post, which includes a spoiler recap for Nightshade, under protection from here.

In Nightshade, Stilwell reflects that you never know when bad luck or bad news are coming:

“Just the year before, there had been a story out of Los Angeles about a so-called amateur sleuth who ended up shot to death in her home office’s closet.”

Me: what? He’s talking about Colleen !!

Remember, Colleen Hatteras, the genealogy researcher who is helping Ballard with a case? Poor Colleen, that was so terrible!

Spoilers for Nightshade

These will not be as long as usual. Sorry – I got this advance copy at the last minute and just want to get this post out!

There are several crimes Stilwell is handling in the book:

  1. the assault of Deputy Dunne by a guy named Merris Spivak as Dunne broke up a bar fight. Spivak is being held at the police substation, or “sub” during most of the book.
  2. the investigation of a body found at the harbor. It’s a young woman with a purples streak in her hair, and she’s wrapped in canvas and weighted down by an anchor.
  3. the theft of a marlin statue from the Black Marlin Club, a private club on Catalina Island
  4. the mutilation of a buffalo, which Stilwell has connected to a mystery tour company on the island

Stilwell is told by Captain Corum, his boss in L.A., to stay out of the murder investigation and tend to the robbery and assault cases.

But as Stilwell investigates the theft of the statue, he also finds the identity of the victim, Leigh-Anne Moss, an employee of the Black Marlin Club who was fired for flirting with the customers.

A CCTV camera

Using the CCTV from the harbor provided by his girlfriend, Tash (the harbor master) he finds another boat that was in the vicinity at the time he suspects the body was dumped: the Emerald Sea.

When he learns that Leigh-Anne died of blunt force trauma, he suspects the missing marlin statue was probably the murder weapon.

He gets access to the Emerald Sea, and finds that a drawstring bag from a sail has been replaced, and mop head and bottle of cleaning fluid are missing.

Stilwell conveys this theory to the team in LA and fills them in. He talks to a former roommate of Leigh-Anne’s and gets a box of her things, which include gifts from several men.

Back to the buffalo case:

Picture of Catalina Island bison
American bison were introduced to Catalina island in 1924 for the filming of a movie and were never removed. Now they’re a popular tourist attraction.

The missing witness to the buffalo incident, Henry Gaston, turns up and is ready to flip on his boss, Oscar “Baby Head” Terranova. Terranova seemed to have ordered Gaston to kill the buffalo to drum up more business for his mystery tour business, and has also paid bribes to the mayor, Doug Allen.

Stilwell holds Gaston at the police substation while he meets with Monika, the DA, who wants to try to get Terranova to testify about corruption.

When Stilwell returns from a meeting with the DA, Spivak has escaped, Gaston is dead, and the deputy in charge is unconscious.

Stilwell realizes that Spivak staged the bar fight so he’d be in jail when they brought Gaston in. It was a planned hit. When Corum tells Stilwell he’s going to let people think Gaston’s death was just an collateral damage of the jailbreak, Stilwell leaks the truth to a local reporter.

Spivak kidnaps Tash. Luckily, Stilwell is able to track her through her phone, which her captor uses to call Stilwell.

He frees her and kills Spivak. Tash puts Spivak’s gun on the floor next to him to better justify the shooting.

Back to Leigh-Anne’s Case

Stilwell goes to talk to Daniel Easterbrook, one of her sugar daddies. He was in love with her and is distraught by her death. He called her “Nightshade” because that was the name of the dye she used to put purple streaks in her hair.

Stilwell has realized that the DA, Monika, knew Spivak from her old neighborhood, and that she must have leaked to Spivak and Terranova.

Stilwell tells the LA team that he does not think Easterbrook killed Leigh-Anne. But when Easterbrook takes his own life, the LA team announces that he killed her, annoying Stilwell.

Monika arranges a meeting with Terranova, who has recordings of his plotting with Mayor Allen.

Stilwell sets up another sting against Charles Crane, the manager of the Black Marlin Club, whom he suspects of Leigh-Anne’s murder. He arrests Crane.

Mayor Allen is indicted on conspiracy to commit murder, and Stilwell also arrests him.

The Ending of Nightshade by Michael Connelly Explained (or not?)

Thanks to Bonnie in comments for pointing out the somewhat cryptic ending. Let’s discuss it!

Who is the second person being transported in the helicopter at the very end of Nightshade?

Before the mayor’s indictment, Stilwell tells his boss Corum that he has two suspects and will need a helicopter to fly them both back to L.A. to be booked.

Stillwell then arrests Mayor Allen and tells his officers “hold the takeoff until I get there with the other custody.” McKay (the reporter) asks “who’s the other custody?” and Stilwell doesn’t answer.

Who is the other person being transported?

I think it’s Charles Crane.

  • In his conversation with Corum, Stilwell suggests that the second person in the chopper is someone he arrested for Leigh-Ann Moss’s murder.
  • Stilwell also reflects that he needs to prepare arrest documentation for both Crane and Allen.
  • Besides that, everyone else is dead (Spivak, Gaston) or cooperating with a deal (Terranova).

The only problem with that is that Stilwell told Crane that his case will be going to Judge Harrell on Catalina island.

My only other guess would be Monika, but she was already in LA handling the mayor’s grand jury session.

Why is Stilwell so mysterious about the second arrest with Lionel McKey? Why is he sending Crane to L.A?

If you have theories (or evidence I missed!) please leave them in comments!

That’s all I have. If you have questions or think I got something wrong (which happens!) please leave me a comment!

Great, but who was the second arrest after the mayor? The one the helicopter was waiting for? I missed something?

Hi Bonnie,
I think it has to be Crane. Not sure why Stilwell is being so mysterious, but I added your question to the bottom of the post and go over all my reasoning there.

Let me know what you think as I’m not 100% sure!

Who else could the 2nd person in the helicopter be but Charles Crane? It was no mystery to me.
As a long time, die hard Michael Connelly fan, I was really disappointed in this book, and can only hope it’s a stand-alone. I couldn’t identify with Stilwell at all, or anyone else in the book at all. I couldn’t wait to finish it and move on to something.
I felt the whole book was a bit forced and just an attempt to add another character to Connelly’s ever growing lineup. I was completely happy with Just Harry Bosch.
If this turns out to be a recurring character,and another Stilwell book follows, it’ll be the first one I’ll skip reading

I thought it was a fair question!

I do agree with you on Stilwell. He reminded me of Ballard, and I find her a little closed-off. I’m very slowly warming up to her, but I’m not sure I’ll ever get there. It’s hard to top Bosch. I’m not sure what the reason is for the standalone. Maybe MC needed a break?

Michael Connelly’s website refers to a “Detective Stilwell” series. I thought that it was okay. I think all of the infighting gets old.

Ooh, interesting. Thanks for sharing. I still think Catalina Island is too small for multiple books, but so was Cabot Cove 🙂

So frustrating and makes no sense that Stil would leave something unfinished: who was the 2nd arrest!!

Thanks for this review with “spoilers.” I was confused by the ending and I am glad there was something to be confused about!
