"The Nine Mile Walk: The Nicky Welt Stories" is a collection of eight short stories penned by American author Harry Kemelman (better known as the author of the Rabbi Small series) for the Ellery Queen Mystery Magazine between 1947 and 1967.
All the stories feature Nicholas ‘Nicky’ Welt, Snowdon Professor of English Language and Literature at an unnamed American university. Welt is an irascible man with a pedagogical manner, dismissive of anything but hard reasoning, is always accompanied by the slightly dim-witted narrator (an unnamed County Attorney), and lives by himself in a boarding house with a landlady who worships him. Reminds you of someone? Yes... Welt is something of a Sherlock Holmes analogue.
Written in the classic tradition of the armchair detective stories of the Golden Age of Detective Fiction, the focus on all the stories lies squarely on the problem, and the principal players involved in the problem. Kemelman does not really bother with setting or characterization much, which ensures that there is absolutely zero fluff in the stories. In all but the first story, Nicky, through his association with the attorney, is presented with the facts of a baffling crime or an open-and-shut case (or is sometimes present on the scene), and through logical inferences alone, comes up with the correct, albeit surprising, solution.
The first story, "The Nine Mile Walk", is one of the classic short stories of detective fiction, owing purely to its structure, where an academic discussion of logical reasoning leads to the solution of a crime to which the reader was not privy in the beginning. The logical structures are more often than not plausible, and even when it's a bit shaky, Kemelman's engaging prose carries the story through.
All in all, a solid 8/10.
