The crew of 'The Express' is one of those ensembles that sticks with you long after the last page. At the center is Jonah Hale, a reluctant
Hero with a knack for reading people and a past he rarely speaks of — part conductor, part sleuth. He's not flashy; he solves problems the way a good mechanic tunes an engine, patiently and with careful hands. Then there's Mara Lin, a sharp-as-a-razor investigative reporter whose curiosity propels much of the plot. Mara's
the one who asks the uncomfortable questions, drags secrets
into the light, and ends up forming a complicated partnership with Jonah that’s equal parts
trust and friction. Rounding out the main trio is Elias “Old-Eli” Mercer, an almost-mythic retired engineer whose stories about the train's past become essential clues; he's like the beating heart of the train, full of warmth but hiding a stubborn streak.
Beyond those three, the novel fills the carriages with vividly drawn characters who matter as much as any protagonist. Detective Isla Reyes is the moral center of the police presence — patient, meticulous, and often frustrated by the bureaucracy she navigates. Her scenes with Jonah highlight the tension between institutional procedure and the messy human instincts that
drive the investigation. Then there's Victor Kline, the antagonist with the poised
smile and chillier motives; he’s not cartoonishly evil but a believable, slippery figure whose influence extends into the city's elite. I also loved Lena Park, a young immigrant worker whose small, brave choices end up shifting the course of the mystery. She’s quietly fierce and represents the novel’s emotional grounding in everyday struggle. Minor but unforgettable players include the punky ticket-seller Rosa, the mysterious night-cleaner Mr.
G., and a brief but pivotal cameo by a violinist who seems to know more than she lets on.
What makes these characters sing is how they change through interaction. Jonah’s cynicism softens when faced with Mara’s relentless empathy and Old-Eli’s stubborn hope. Mara confronts some of her own compromises in journalism when Isla exposes the human costs of headline-
chasing. Victor’s calm unravels in small, glorious ways that reveal a history tied to the very rails the train ride takes — that layered backstory gives the conflicts more bite than a simple whodunit. The novel also does a great job balancing screen-door tension (
suspense, traps, chase sequences) with
quieter human moments — a shared cigarette on a rain-soaked platform, the clack of the rails as characters
confess, a lullaby hummed into the night car. Those little beats let you breathe and then slam you back into the mystery.
all in all, reading 'The Express' felt like riding a train that knows exactly where you’re headed but still surprises you with the scenery. The character dynamics are the engine, and every side character adds a new car to that train — sometimes rickety, often beautiful, and always necessary. I found myself cheering for Jonah and Mara, resenting Victor, and feeling oddly protective of Lena and Old-Eli by the last chapter. It’s the kind of cast that keeps me turning pages and thinking about them days later, which is exactly the kind of novel I live for.
