Located on Sweden’s southern coast, overlooking the Baltic Sea, the small town of Ystad is an idyllic sort of place, with flower-filled cobblestoned streets and half-timbered houses that reflect its medieval origins. It’s not the sort of place you’d associate with murder and mayhem, but thanks to author Henning Mankell’s bestselling series of crime novels about police detective Kurt Wallander, Ystad is now known as much for mystery as it is for history.
