Midwinter: Certain travellers in old England is a 1923 historical novel by the Scottish author John Buchan. It is set during the Jacobite rising of 1745, when an army of Scottish highlanders seeking to place Charles Stuart onto the English throne advanced into England as far South as Derby. The Prince, otherwise known as "Bonnie Prince Charlie", the grandson of the ousted King James II, required men and money from English Jacobite sympathisers, and the novel imagines why those were not forthcoming from landowners in the Western counties and Wales. It purports to sheds light on Samuel Johnson's previously unknown activities during that period.
