Sometimes a movie (or a book, or a series, or whatever) comes along with a premise that you wonder why someone hasn’t thought of sooner (with the inevitable caveat that, sometimes, someone has and you’re just not aware of it). The Kid Detective is one of those occasions (or was for me, at any rate) — what would a ‘kid detective’ (you know, like the Hardy Boys or the Famous Five or whatever) be like when they grew up?

There’s a few different ways you could spin a setup like that, and here writer-director Evan Morgan takes a fairly realist approach: the “kid detective” in question, Abe Applebaum, was a quirky story for the local paper when he was a child, investigating “mysteries” of the schoolyard variety; but when a real crime takes place and he (unsurprisingly) fails to solve it, that’s the end of the fun and games. Nonetheless, as a 32-year-old adult (played by Adam Brody), Abe has tried to keep his childhood fantasy going, running a real detective agency. Except there’s not much to actually investigate in a small town, and the fact he’s never grown up leads to derision from all around, rendering him a miserable washed-up has-been. So when a high schooler (Sophie Nélisse) asks him to investigate the murder of her boyfriend, Abe sees a chance to finally prove himself.

When I say “a premise you wonder why someone hasn’t thought of sooner”, I suppose what I also implicitly mean is “something I am interested in”; something that scratches an itch I didn’t even know I had. Of course, that automatically creates expectations — even if you can’t state them exactly, you now have a notion of what you want out of this thing; of the itch that needs to be scratched. Fortunately, The Kid Detective was everything I expected it to be and more. It’s a successfully amusing extrapolation of its premise. It kind of has to be a comedy, because the basic idea is too silly to take seriously in the ‘real world’, and it manages that without tipping over into farce. But, somewhat remarkably, it’s also a solid mystery in its own right, with a surprisingly moving conclusion. It’s a balancing act that shows the validity of comedy-drama (aka dramedy) as a tone. It’s a mode that’s sometimes dismissed as “not funny enough to be a comedy, not affecting enough to be a drama”, but when it works, it’s arguably more like real life than either of those extremes.

It also doesn’t mean the film has to play broad. Take Brody’s performance, for example: he balances the sardonic humour and introspection just right, rendering Abe believable as someone who is actually pretty darn clever but has lost his way and self-belief. Or there’s the ‘big denouement’, which is just two characters sat at a table talking. It’s both relatively understated and means the finale arrived at a point where I (at least) wasn’t quite expecting it, making it all the more effective and powerful. With hindsight, maybe I should have seen where it was going, and so maybe you could argue the film suckered me. But, you know what, I’m glad it did. It’s nice to be surprised by a mystery’s resolution. It happens too rarely as you get older and become narrative-savvy and everything’s predictable. One moment even gave me goosebumps, and you’ve got to love anything that can elicit such a physical reaction.

Clearly, I was the target audience for this. I couldn’t have told you I wanted it, but when I heard about it I was eager to see it. As I said, that has both pros and cons: to the former, I’m ready to be won over; to the latter, raised expectations can lead to disappointment. Fortunately, The Kid Detective aces it and I loved it.

The UK TV premiere of The Kid Detective is on Film4 tonight at 9pm, and available to stream on Channel 4’s catchup service for 30 days afterwards.

It was #147 in my 100 Films in a Year Challenge 2021, and placed 4th on my list of The Best Films I Saw in 2021.
