Even before the sad death of John Pugmire, who brought us much in the way of foreign language impossible crime novels through Locked Room International, Pushkin Vertigo had started some heavy lifting in supplying us with ingenious puzzle plots from the other side of the language barrier. They’re not all bangers, of course, but the commitment Pushkin have shown, and continue to show if the raft of upcoming titles on their slate is anything to go by, is heartening for those of us who love a complex problem rigorously exploited. And The Labyrinth House Murders (1988) by Yukito Ayatsuji, recently translated by the talented Ho-Ling Wong, is certainly that.
