The Laurentian Mountains (French: Laurentides) are a mountain range in southern Quebec, Canada, north of the St. Lawrence River and Ottawa River, rising to a highest point of 1166 metres (3,825 feet) at Mont Raoul Blanchard, north east of Quebec City in the Reserve Faunique des Laurentides. The Gatineau, L'Assomption, Lièvre, Montmorency, Nord and St. Maurice rise in lakes in this mountain range.

Across the U.S. border to the south, the Adirondack Mountains in New York State are actually an extension of the Laurentians, although they are sometimes mistakenly included with the Appalachian Mountains.

Note that although one of Quebec's official regions is called Laurentides, the mountain range runs through four other regions; Capitale-Nationale, Outaouais, Lanaudière, and Mauricie. The foothills of the Laurentian range extend into Northeastern Ontario, particularly towards Bonnechere, Ontario as the Laurentian Highlands, Madawaska Highlands, a range of hills near the Madawaska River and Opeongo Lake, and the Opeongo Hills (another range of high hills, near Round Lake) in Ontario near the town of Combermere.

The Shadow is a collection of serialized dramas, originally in pulp magazines, then on 1930s radio and then in a wide variety of media, that follow the exploits of the title character, a crimefighting vigilante in the pulps, which carried over to the airwaves as a "wealthy, young man about town" with psychic powers. One of the most famous pulp heroes of the 20th century, The Shadow has been featured in comic books, comic strips, television, video games, and at least five motion pictures. The radio drama is well-remembered for those episodes voiced by Orson Welles.

Introduced as a mysterious radio narrator by David Chrisman, William Sweets and Harry Engman Charlot for Street and Smith Publications, The Shadow was fully developed and transformed into a pop culture icon by pulp writer Walter B. Gibson.

The Shadow debuted on July 31, 1930, as the mysterious narrator of the Street and Smith radio program Detective Story Hour. After gaining popularity among the show's listeners, the narrator became the star of The Shadow Magazine on April 1, 1931, a pulp series created and primarily written by the prolific Gibson.
