A short story from the British Library Crime Classic collection The Edinburgh Mystery. ‘The White Line’ appeared in a 1929 anthology, The World’s 100 Best Detective Stories, and features John Ferguson’s Scottish series detective, criminologist Francis McNab. Returning to England from Washington, McNab becomes embroiled in a mystery aboard the ship and must get to the bottom of who stole eligible socialite Sally Silver’s diamond necklace before they reach the port.

From the Highlands to the borders, the bustling cities to the remote isles in cold seas, the unique landscapes and locales of Scotland have long inspired writers of the very best Golden Age mysteries. Beginning with the adventures of Sherlock Holmes from Edinburgh-born Arthur Conan Doyle, this new collection includes the ingenious scientific mysteries of Anthony Wynne, the dark and sardonic work of Margot Bennett and contributions from neglected yet brilliant authors such as Scobie Mackenzie and R. T. Campbell.
