The Toll-Gate is a Regency novel by Georgette Heyer, which takes place in 1817.

Unlike many of Heyer's historical novels which concentrate on a plucky heroine, this one follows the adventures of a male main character, an ex-captain in the British Army who has returned from the Peninsular War and finds life as a civilian rather dull. The setting for this detective/romance story is in and around a Toll-Gate in the Peak District, vastly different from the elegant backgrounds of
London, Bath, Brighton, or some stately home.
