Welcome to my weekly segment, Waiting on Wednesday, where I look at upcoming books that I am planning to order and review in the next few months and which I think I will really enjoy. Stay tuned to see reviews of these books when I get a copy of them. In this week’s Waiting on Wednesday, I check out an intriguing, upcoming murder mystery that is going to be a highlight of early 2026 with Jigsaw by Jonathan Kellerman.

Of all the murder mystery authors I have had the pleasure of reading and reviewing since I started my blog, few have consistently impressed me as much as Jonathan Kellerman. A veteran of the crime fiction genre, Kellerman has written a huge array of compelling novels throughout his writing career, including some very gripping reads. His main body of work is the iconic and long-running Alex Delaware series, which follows the titular protagonist, Alex Delaware, a child psychologist, who works with his best friend, LAPD Lieutenant Milo Sturgis to investigate unusual or complex cases around Los Angeles.
The Alex Delaware novels are a classic and captivating crime fiction series, and Kellerman has written a huge number of them over the years. I became a fan of the series myself a little more recently, when I was lucky enough to grab a copy of The Wedding Guest back in 2019. A very cool novel with a great case behind it, The Wedding Guest was a fantastic introduction to the author and the Alex Delaware novels, and I ended up going back to the series the following year to read The Museum of Desire. This great novel was also outstanding, and it impressed me enough to make the Alex Delaware series a must-read addition to my annual reading schedule. I have since gone on to read every new Alex Delaware novel that followed, including Serpentine, City of the Dead, Unnatural History, The Ghost Orchid, and Open Season. All these novels were extremely amazing, and I have had an exceptional time with all of them.
Due to how much fun all the previous novels were, I am always very keen to get my hands on the next Alex Delaware novel, and we already have some details about the 2026 addition to the series, Jigsaw. Jigsaw will be the 41st book in the Alex Delaware series and will force Alex and Milo to investigate two separate, complicated murders that have an unlikely connection.
Plot Synopsis:
When a young woman is found dead at her kitchen table – with DNA belonging to her ex-boyfriend at the scene – psychologist Alex Delaware and Detective Milo Sturgis assume it’s an open-and-shut case.
But the guy has an airtight alibi. Could an enemy from his shady past have framed him?
Many miles away, a former LAPD officer is found brutally murdered in her garage. Her co-workers knew her as meticulously organized, but her house is full of junk and meaningless objects – except for the envelopes full of cash hidden within the chaos…
But as Alex and Milo dig deeper, they discover shocking links between the victims. It soon becomes clear they have a complicated – and deadly – puzzle to solve.
Based on the above synopsis, it sounds like Jigsaw is going to be another excellent entry in this great series. I am already quite intrigued by the hinted plot, and Kellerman clearly has quite an outstanding mystery brewing for his 41st Alex Delaware novel. Two seemingly unconnected murders with unique circumstances running at the same time is the great basis for an addictive crime fiction read, and I look forward to seeing the protagonists dive into both compelling victims with the author’s typical methodical, character-focused, style. While I am curious about both murders, including one featuring an obvious, but clearly innocent suspect, and the other with an unlikely hoarder, the true test of this novel is how the author will bring both separate murders together into a single storyline. I honestly have no doubt that Kellerman will come up with a clever link between both cases, and this will likely result in Jigsaw being an outstanding and very impressive addition to one of my favourite crime fiction series.
Due to how much fun I have had reading Jonathan Kellerman’s previous novels, Jigsaw is a highly anticipated book for the first half of 2026, especially with its intriguing synopsis. Kellerman has never failed to wow me with his compelling mysteries, and Jigsaw already looks set to be an incredible read. I honestly can’t wait to get my hands on the next Alex Delaware novel, and I already know it is going to be amazing.
