Start with The devotion of suspect X. A woman kills her ex-husband in a moment of panic; her neighbour, a lonely maths teacher of extraordinary ability, offers to handle the aftermath; and the novel then pits him against the physicist Manabu Yukawa, who happens to have known him at university. You are told who did it in the first twenty pages. Everything afterwards is the pleasure of watching two brilliant men try to out-think each other over a problem only one of them can bear to solve.
The obvious alternative is to read Higashino in Japanese publication order, and it is not available to you. Only a fraction of his sixty-plus novels have been translated, and they came out in English in an order bearing almost no relation to the originals — Malice was published in Japan in 1996 and in English in 2014, Journey Under the Midnight Sun in 1999 and 2015. Trying to reconstruct Japanese order means starting on books that do not exist in English. Read the English sequence instead; the series carry so little continuity that you lose essentially nothing.
The Detective Galileo novels
This is the series the physicist Yukawa anchors, and the three translated novels are best read in the order they appeared in English.
The devotion of suspect X is first and best.
Salvation of a saint is second: a man is poisoned in his own home, the obvious suspect was several hundred kilometres away, and the how is impossible for most of the book. It is an ingenious construction, and it is fair to say that a good number of readers find the final mechanism a stretch too far. Enjoy the cat-and-mouse and hold the solution lightly.
A Midsummer's equation moves Yukawa to a declining seaside town facing a seabed-mining dispute, and pairs him with a boy staying at a family inn. It is the gentlest of the three and the most interested in place and consequence rather than trickery. Some readers rank it the most humane thing Higashino has written; others find it slow.
In Japan the Galileo series began with short-story collections that have never been fully translated, so the English sequence starts partway in. Nothing in the novels depends on them.
The Kaga Kyoichiro novels
Detective Kaga is the other recurring figure, and this is where the translation order gets genuinely strange.
Malice is a writer's murder investigated through competing written accounts — a diary, a manuscript, a confession — where the question stops being who and becomes why, and then stops being why and becomes whether anything you have read is true. It is the fourth Kaga novel in Japanese and the first in English, and it works completely on its own.
Newcomer is the eighth in Japanese and reads like a fresh start, because it is structurally unusual: Kaga, newly transferred to the Nihonbashi district, works one murder through a sequence of near-standalone chapters, each solving a small domestic mystery about a local shop or family before the larger case resolves. It is the warmest book of the six and the least like a thriller. Read it after Malice but do not expect the same thing.
The standalone
Journey Under the Midnight Sun is the outlier and the hardest. It follows two children across nineteen years from a 1970s Osaka pawnshop murder, told almost entirely from the outside, with the two central figures kept at a deliberate distance for five hundred pages. There is no companionable detective, no comic relief and very little warmth. It is his most ambitious book and the one most likely to be abandoned. Read it last, and only if the others worked.
Where to stop
If The devotion of suspect X does not land, stop there — it is the best book he has in English, and the others are variations on the same instinct. If it does land, three more will follow easily. Find more crime and mystery reading paths on Discover.
