Whatever Railway Detective James (Jim) Stringer lacks in cleverness, he makes up for in dogged persistence. Murder at Deviation Junction is no exception to the rule. The cleverest aspect of the entire plot is when he uses a thief to catch a murderer by gaining evidence from a “fence.” Otherwise, he doesn’t read character well, walks blindly into traps or ambushes, and has trouble figuring out ways to circumvent his incompetent superior’s unreasonable demands.
Alas, Stringer is present when a body is recovered under a heavy snowfall. Said deceased individual seems to have hanged himself, but that’s only (as so often in a mystery) the easy way to close the case. Stringer refuses to quit working on the case because he is certain that something is wrong. Yet, he finds himself risking not only his pending promotion but his entire job in order to follow the tenuous and conflicting leads he is following.
Unlike the earlier books in the series, there is (what feels to me like) a non sequitur in the plot. The murderer has an opportunity to flee from the country with reasonable assurance that no one will be the wiser. Yet, said murderer is so committed to wiping the slate perfectly clean (so that even those who are bribed don’t get a chance to change their minds) that he ends up having to make things worse. I can’t say anything more without causing several spoilers, but at some part in the book, you’ll wonder why a certain character didn’t just hot foot it and get out of the jurisdiction she/he was in and into a country with no extradition agreement. Today, that would be easier said than done, but I think extradition was rather “iffy” and inconsistent in the early 20th century (although the country to which the offender was planning to flee in the book would have likely granted extradition to Britain from the middle of the 19th century forward), so it isn’t perfect.
As usual, Stringer’s background as a railway fireman serves him well in his detecting duties along the rails. He knows equipment, procedures, timetables, signals, and, in one scene, even how to perform his old work as a fireman in order to save his life (Oh, was that a spoiler?). I may complain about Stringer’s actual “detecting” process, but that doesn’t stop me from reading all the novels in the series.
