Last One to Leave (2022) by Benjamin Stevenson

Benjamin Stevenson's first two Ernest Cunningham novels, Everyone in my Family has Killed Someone (2022) and Everyone on this Train is a Suspect (2024), are not only the two highlights of 2025, but represent another step towards a Second Golden Age for the detective story – only the holiday theme kept from dipping into the third novel. I realize it has been a newly established tradition for Christmas to come earlier, and earlier, each year, but figured a review of Everyone this Christmas has a Secret (2024) would still be on early side.

So decided to hold off on Everyone this Christmas has a Secret, until at least the leaves start to turn brownish. Fortunately, the Ernest Cunningham series is not Stevenson's first stab at the detective story. Stevenson wrote two novels about disgraced TV producer Jack Quick, She Lies in the Vines (2019) and Either Side of Midnight (2020), of which the second is an impossible crime novel concerning a shooting on live television ("One million witnesses... One impossible murder"). That one is currently on the big pile, but there are also two short novels, Find Us (2021) and Last One to Leave (2022), collected under the title Fool Me Twice (2024). Last One to Leave sounded like an intriguing take on the classically-styled detective story with a modern framing. Or, to be more precise, the premise struck me as specifically tailored for playing the Grandest Game in the World.

Ryan Jaegan is a widowed father of a 12-year-old daughter, Lydia, who entered his name for competition thrown by a notorious Youtube channel, CashSmashers. A channel with millions of subscribers, hundreds of millions of views and a major sponsorship from a gambling company, providing them with ample resources to pull some outrageous stunts – like dropping parachutes with sacks of money from a helicopter ("they were chasing clicks and views, after all"). They also do competitions with big money prizes. Such "Last One to Leave" contests where a group holds on to a luxury car with the person who holds on to it the longest gets to keep it. Ryan has little money and has debts with the wrong kind of people. So reluctantly agrees to participate and finds himself competing with six other people for a clifftop mansion worth four million dollars.

This contest is similar to the car contest, but much more involved with more room and opportunities for shenanigans. The rules are deceivingly simple: each contestant places one of their hands on a wall and, from there, they're free to roam and move around as much as they like as long as their hand continues to touch the house. Last person to let go wins the four million dollar mansion. Ryan is not the only one there to win the game and the CashSmashers team aren't above manipulating the contest, because "they need high drama, big twists, to make things viral."

So two days and several eliminations later, sleep deprivation, muscle cramp and lack of food begin to take toll, but Ryan and the remaining participants get really tested when one of them turns up apparently dead – lying next to the bag of money with a knife sticking out of him. Is it really a real murder or simply the CashSmashers stepping of their game now that the remaining contestants are vulnerable? They told them over the speakers to keep playing, but what if the body is real? But how can "you commit a murder unseen in a house full of cameras" where everyone's movement is restricted to the length of their arms?

The solution to the impossible stabbing does not disappoint. Not merely as a clever new wrinkle on the "invisible assailant" impossibility, but the cleverly-hidden, fairly clued and foreshadowed murderer complete with a very fitting motive. That's impressive considering Last One to Leave is basically short, tightly packed novella/short novel playing out like a tale of suspense, but framing the story and plot as a closely controlled, constantly surveillanced contest allowed Stevenson to play up/exploit both the suspense and puzzle elements simultaneously. A good example is how the characters refuse to take their hand off the wall when faced with emergencies and even a possible murder, which also helps to enforce the impossibility of their situation. And makes for one hell of an ending when Ryan exposes the murderer!

What I liked even more than the superb blending of suspense with an excellently played out impossible crime, is to get another fine example of a good, old-fashioned detective story with a gritty, contemporary setting, characters and motivation – fitted together as naturally as a dagger, stingy patriarch and a locked library. Last One to Leave was very reminiscent of A. Carver's The Dry Diver Drownings (2024) in that regard, in which a bunch of YouTubers chase clicks, but, instead of a crazy contest, it's about shooting a creepypasta video interrupted by several locked room murders. So glad to finally see these type of (locked room) mysteries appear in the West, because it's something I have come to associate with Japanese shin honkaku mystery writers and anime-and manga mysteries over the years. Yes, whether you like suspense and thrillers or the puzzle-oriented detective story and locked room puzzles, Stevenson's Last One to Leave has it all in a compact, well-paced story. One for the 2025 best-of list!
