I read this book because the title and cover are amazing. It belongs in a museum. Amazing concept for a novel.
I am only half joking. It is absurd, but the core of the Columbo character is that he is an aloof disheveled man who gets into high stakes situations and does things that seem far beyond his capabilities. Logically, I can see why a writer would think this is an appropriate escalation of that premise. The biggest positive I can give is that Columbo does, for the most part, act how you would expect him to. Similar to some less than stellar episodes of the show, his presence alone can keep you engaged. Still, while it is serviceable in that department, my compliments do not go much further.
This entire review is marked spoilers because the ending is the book's biggest sin. It makes me unable to recommend the novel to even a hardcore Columbo fan, and I therefore must spoil it. Here it goes: Columbo does not solve the mystery. I assume this was to avoiding breaking the realism of the Columbo world. To this I would say: "who cares? Look at what you are writing". In a pulpy novel of this type the murder must be solved. It is as simple as that.
The long and short of it is this: a casino owner, whose business was affected by JFK's decisions, had the president killed. Paul Drury, a talk show host, came close to cracking this case. Unfortunately for Drury, his wife had debts at the aforementioned casino and was blackmailed into murdering him.
A few big problems here. First, it actually suggests that the second shooter was unrelated to the first, which makes the whole grand conspiracy feel rather small and nonsensical. Second, if they were able to successfully target a president, why do they need to go through all this trouble and leave such a paper trail just to get a small time celebrity like Drury? Third, and this one is quite hard to forgive, it seems too coincidental that his wife would just happen to owe debts to this casino, and that multiple shooters would fire at the same time for no particular reason on that day in 1963. Coincidence plays a large part in these events.
There are a few intriguing elements. I enjoy the idea that a hacky talk show host who regularly milks JFK's murder would actually stumble across the real solution and pay the price for it. Plus, you can tell Harrington knows quite a bit about the JFK murder and is able to dole out the details in the systematic and disconcerting way you would expect of a mystery novel.
I also think the idea that Columbo solves JFK's murder purely because he needs to in order to solve a less significant crime, implying he could have done so any time he wanted, is quite funny. It is a very exaggerated version of the character that makes him into some Sherlock Holmes level savant, but it's a bit of fun. Novels being used to explore different interpretations of classic characters is just fine to me, and it's "non canon" anyway.
That's about it for the positives. Sadly, the negatives are unforgiveable.
Besides the bad ending and nonsensical plot, Columbo uses AI photo enhancements to "solve" blurry photos. This is how he ultimately comes to all his most important conclusions. I suppose this must have been a new thing at the time the novel was written, but even given that context it still seems very boring. Surely even audiences at the time wanted Detective Columbo to solve the mystery, not a computer.
Some other elements also seem quite out of place in a Columbo story. He is interacting with women blackmailed into sex work and is flying over state lines to interrogate high level mobsters completely on his own. It comes off as somewhat grimy rather than adventurous.
As I've mentioned, the world feels very small. Columbo did not have to look far to find the most famous assassin of all time and the suspect is not a very physically dangerous man, nor does he have a wide network that poses any real threat to Columbo. This should be a thriller, but doesn't feel like one. Vegas seems empty, and the plot exceedingly simple.
Overall, I can't recommend the novel, but its existence is fascinating and the main character intriguing. I need to give it two stars just because I nearly read this cover to cover, and that's got to count for something. A huge Columbo fan will get a small amount of entertainment out of this.
