Hansom Cab

The hansom cab, a quintessential Victorian conveyance with its two-wheeled, one-horse design and elevated driver's perch, emerges in 'The Adventures of Sherlock Holmes' as a symbol of swift urban mobility in gaslit London. Though not evolving dramatically across the series, it remains a staple in Sherlock Holmes' pursuits, embodying the era's ingenuity and the detective's reliance on everyday transport for high-stakes chases. Its frosted side windows and nimble handling underscore the gritty, atmospheric backdrop of Holmes' world, with no significant changes noted in later books.
