The Rabbit Factor is the first novel in the Rabbit Factor series by award-winning Finnish author, Antti Tuomainen. It is translated from Finnish by David Hackston. Within a few days in late September 2020, Henri Koskinen has lost his actuarial job, his brother, Juhani, and inherited an Adventure Park on the outskirts of Helsinki. Worse still, when he takes a quick look, he discovers that YouMeFun, despite being a relatively successful business, has a mountain of unpaid bills and a massive loan to repay.

Henri was never really close to Juhani, who had more in common with their chaotic parents. “Juhani was fun and flexible. Humorous and quick-witted. Spontaneous and amiable” while Henri “had only one deep-held wish. I wanted everything to be sensible”

“He used to joke, saying I would die of stiffness. I told him I was very much alive and not at all stiff, I just wanted things to occur in a good, logical order and that I based all my actions on rational thinking” but now Henri wishes he knew more about his brother, and what Juhani could possibly have done with so much money.

Even before he has met all the staff and had a decent look at the books, a reptilian organised-crime type and his heavy turn up to demand payment of his brother’s two-hundred-thousand-euro debt, with interest. Not that Henri has the money to pay but, as an actuary, what he really objects to the exorbitant interest rate: ten per cent over just two and a half weeks? Henri narrowly escapes losing a finger, but he knows that won’t be their last visit.

Sure enough, a few days later, as he’s trying, after hours, to repair the broken ear on a giant rabbit statue, a nasty fellow with a knife (or two) turns up to deliver him an unambiguous message. Another narrow escape that sees Henri taking action he could never have envisaged when he was working for the insurance company, and he really has to figure out something to get them off his back.

What is really puzzling is how Knife Man knew Henri was there alone, and how he got into the park. Juhani gave the staff free rein with running the place: could one of them be in cahoots with the crooks? They are an unusual bunch, and Henri knows his directness can be off-putting:
“‘I can be frank with you, yes?’
‘I believe it’s for the best,’ I say. ‘Some people say it can be rude, but I think the benefits far outweigh the possible drawbacks. I’m not sure of the exact ratio, but in my experience I can say that the probability of causing offence can’t be higher than ten percent. That gives being frank around a ninety-percent chance of success. Those are exceptionally good odds.’”

Needing to pay the loan, the bills and trying to keep the adventure park running, Henri comes up with a bold plan and presents his criminal creditors with an audacious proposal, the sort only an actuary could convince the big man will be viable. His radical idea includes starting a bank and offering park patrons pay-day loans, but can it really work?

As if he doesn’t have enough on his plate, the reptilian guy tries to blackmail him, someone might be sabotaging park structures, and he finds himself falling for the park’s manager. Laura Helanto is an artist whose murals are transforming the park and have Henri inexplicably fascinated. The mathematician in him tries to analyse why, without success. Oh, and a Helsinki Police DI is looking for Knife Man…

As well as the artist, his team consists of Kristian (a maintenance man who was promised the position of General Manager), Minttu K (an alcoholic marketing and sales manager), Esa (a head of security who wants to be a US marine), Samppa (an earringed, tattooed children’s entertainer), Johanna (a fitness-freak café manager) and Venla (a ticket-seller who has yet to turn up for work).

There’s plenty of humour in this novel, some of it quite black, and a delicious irony when Henri uses the exact same touchy-feely language that drove him from his last job to handle Kristian’s promotion demands. Henri will remind some readers of Don Tillman: with his reliance on maths and logic, his imaginative problem solving and good intentions. More of this protagonist, in The Moose Paradox, will be most welcome. Recommended!
