John Macnab by John Buchan

Three prosperous but restless friends, bored with comfortable lives, concoct a bold sporting wager to restore their zest: under a single anonymous name they notify several Highland landowners that they will attempt to take specified prized quarry from their estates. The ensuing cat-and-mouse game — carried out with the help of a resourceful local and complicated by a burgeoning romance and questions of honor, legality and courage — tests their skill, nerve and character, leading to risky exploits, moral reckonings and renewed camaraderie.
