Barkeley Blake was a paleontologist who thought he had discovered a large dinosaur bone in the badlands of Alberta Province. The bone was actually constructed of concrete and planted by another explorer. When one of Blake's employees pointed out the fraud, Blake killed him. He had already sold the "bone" to an museum and planned on having it "stolen" enroute to eastern Canada. The false artifact fell into the possession of Mary Ann McConnell, an another employee of Blake, whose career he had hampered. McConnell blackmailed Blake.
The name of this character may be a nod to historic palaeontologist Barnum Brown, who was active in the Alberta badlands circa 1910.
