From the iconic Orient Express to the shadowy alleys of urban noir, and to the contemporary invisible highways of cyberspace, transportation and mobility have long played an important role in crime fiction. Traditional detective fiction often relied on transportation as both setting and symbol, underscoring how mobility can conceal, isolate, or reveal, shaping the very structure of mystery and detection. In the digital age, mobility is no longer confined to physical movement; it also encompasses virtual travel, data flows, and algorithmic surveillance. This thematic issue invites contributions that explore how crime narratives—from classic detective stories to contemporary thrillers, from global noir to genre-bending narratives—engage with both literal and metaphorical forms of movement, consider transportation as a backdrop, a plot device, and/or as a lens through which to examine broader cultural, social, and psychological dynamics. We are particularly interested in how mobility intersects with issues of identity, memory, belonging, and transgression, and address both physical travel and digital mobility.
