The main character of the book, a man of thirty, lives in a modest flat on the fifth floor of a housing block. Every Sunday, the protagonist performs a kind of ritual : he climbs onto the window ledge and waits for a suicidal urge, which, however, never comes.

The events of the novel unfold over the course of three days. On the first day, the young man sets off to the town’s railway station in search of prostitutes. On the way, he runs into another young man, known during the story as the “bloke with the orange braces”, who has hanged himself from an old steam engine in an unused siding. The protagonist saves him and takes him to the station hospital, from where the bloke with the orange braces discharges himself on his own two feet. The main character will later find the man he saved in a railway workers’ bar. He is unwillingly embroiled in a fight provoked by the bloke with the orange braces, who breaks a chair over the head of one of the prostitutes in the bar, leaving her in a pool of blood. For the second time in the space of the same day, the protagonist saves the bloke with the orange braces, this time from the fury of the drinkers in the bar, and takes him back to his own flat. This is where the entire atmosphere of the story takes shape : a disabused world of strange neighbours and a building superintendent who is an old woman yearning for a relationship with a young man of thirty.

During the other two days covered by the action of the novel, we discover that the young protagonist is a member of a kind of club for “professional suicides” – people in search of death, sometimes for the most stupid reasons and in the most bizarre ways : one wants to kill himself by sleeping with as many women of easy virtue as possible, in the hope of contracting a fatal disease ; another wants to commit suicide by drinking huge quantities of the finest quality whiskey, until he falls into an alcoholic coma ; etc. They are all “suicide artists”, and it is into this strange group that the young man of thirty would now like to introduce his new friend. Parallel to these events, the two attempt to find out whether the prostitute in the bar has managed to survive being hit over the head with a chair. The answer will not be revealed until the end of the novel.

The finale closes the circle of the tale : during a further visit to the railway station, the protagonist discovers that the prostitute has died. He does not tell his new friend about this. At the same time, however, frightened at the turn that events have taken, he comes up with a plan: he convinces the bloke with the orange braces to go to the station, to the locomotive where he first found him. And he proposes that they both commit suicide. The young man tells his companion that in this way the railway workers will understand that they both regret the incident with the prostitute – and they will be forgiven. In fact, the protagonist’s plan is to free himself from the noose and to chase away anyone who tries to save the other, allowing him to die and thereby escaping from any legal consequences of his association with the prostitute’s murderer. The plan fails, however, for various reasons – the protagonist does not allow his new friend to die, but rather tells him the truth about the prostitute and about what he has been planning. It all ends with a roar of laughter, an agonised roar of laughter which consecrates the general principle and theme of the book, according to which whoever has failed at everything else in life can only be consistent and fail at his own death.
