"The crevice... that infinitesimal crack through which the truth will eventually seep."
I hit that line somewhere around hour three, curled up in the back corner of the library after closing. Just me, the emergency lights, and Shirley Jackson (the cat, not the author—though honestly, the vibe was very much her territory). The building settles at night in ways that make you hyperaware of every creak. Perfect conditions for a mystery about a dead financier and the secrets rotting beneath his respectable facade.
Here's the thing about early 20th century detective fiction—it operates on different rules. The pacing feels almost leisurely by modern standards, the dialogue formal in ways that can read as stiff if you're not prepared for it. But when it works? When you lean into that era's particular brand of methodical investigation? There's something deeply satisfying about watching a detective actually detect.
Henry Blaine Earns His Reputation
The setup is classic Golden Age: Pennington Lawton drops dead, apparently from heart failure, and his daughter Anita discovers dear old dad was about to go spectacularly bankrupt. Her inheritance? Gone. His reputation? About to be dragged through the mud. Enter Henry Blaine, detective, and the slow unraveling begins.
What makes this more than a period piece curiosity is the collaboration behind it. William J. Burns wasn't just some pulp writer cranking out potboilers—the man ran the Bureau of Investigation before it became the FBI. His cases were real. The procedural details, the way Blaine approaches evidence, the methodical dismantling of alibis—there's an authenticity here that purely fictional detectives can't quite match. Isabel Ostrander brought the narrative craft, Burns brought the tradecraft. An unusual partnership that actually works.
Is the mystery predictable? Yeah, somewhat. I'd clocked the general shape of the solution by hour five, and anyone who's consumed enough of this genre probably will too. But here's my defense of predictability in classic detective fiction: the pleasure isn't always in being surprised. Sometimes it's in watching the mechanism work, seeing how the detective gets from suspicion to proof. The journey matters more than the destination.
J.M. Smallheer Commits to the Era
The narrator commits. That's rare.
Smallheer doesn't try to modernize the material or punch it up for contemporary ears. The emotional delivery feels period-appropriate—restrained where it needs to be, heightened during the melodramatic beats that the era demanded. Anita's distress reads as genuine rather than overwrought. Blaine's confidence never tips into arrogance. It's a performance that respects both the source material and the listener's intelligence.
At just over eight hours, this is a solid weekend listen. Not quite bedtime material—the mystery requires enough attention that you can't drift off—but perfect for a rainy Saturday when you want something engaging without being exhausting.
The Cracks in the Foundation
I won't pretend this is flawless. The pacing drags in the middle section, where Burns and Ostrander seem more interested in demonstrating investigative technique than in maintaining tension. There's a stretch around hours four and five where I found myself checking the progress bar more than I'd like to admit. The violence, when it comes, is tame by modern standards but might still catch you off guard if you're expecting pure drawing-room mystery.
And look—if you need your mysteries to subvert expectations, to twist and double-back and leave you gasping, this isn't that book. The Crevice is comfort food for a very specific palate. The literary equivalent of a crackling fire and a strong cup of tea. Cozy in its way, despite the murder.
Who's Going to Love This (And Who Should Walk Away)
If you're a Golden Age mystery devotee, someone who appreciates Agatha Christie's puzzle-box plotting or Dorothy Sayers' procedural attention, you'll find a lot to enjoy here. I got that same satisfaction from the methodical investigation in In the Drink, though that one's got a more contemporary edge. The historical curiosity factor—an actual pre-FBI investigator contributing his expertise—adds a layer of interest that pure fiction can't replicate.
Skip it if you need your thrillers to actually thrill. If slow-burn investigation feels like watching paint dry to you, eight hours of methodical detective work isn't going to convert you.
My podcast listeners who love the history of the genre? They're going to eat this up. Everyone else? Know thyself.
Closing Time in the Stacks
The Crevice is a time capsule—imperfect, occasionally predictable, but genuinely interesting for what it represents. The collaboration between a real detective and a skilled fiction writer creates something that feels both authentic and readable. Smallheer's narration elevates the material without trying to reinvent it.
Shirley (the cat) fell asleep by hour six. I kept listening. Take from that what you will.
