βNever had I been given a tougher problem to solve, and never had I been so utterly at my witsβ end for a solution.β β©A signalman is found dead by a railway tunnel. A man identifies his wife as a victim of murder on the underground. Two passengers mysteriously disappear between stations, leaving behind a dead body. β©Trains have been a favourite setting of many crime writers, providing the mobile equivalent of the βlocked-roomβ scenario. Their enclosed carriages with a limited number of suspects lend themselves to seemingly impossible crimes. In an era of cancellations and delays, alibis reliant upon a timely train service no longer ring true, yet the railway detective has enjoyed a resurgence of popularity in the twenty-first century. β©Both train buffs and crime fans will delight in this selection of fifteen railway-themed mysteries, featuring some of the most popular authors of their day alongside less familiar names. This is a collection to beguile even the most wearisome commuter. β©Martin Edwards is series consultant for British Library Crime Classics.
