Synopsis by Hans J. Wollstein
As chapter seven of The Vigilantes are Coming reveals, rather than perish in the explosion of the powder-laden wagon, Don Loring, aka "The Eagle" (Robert Livingston), jumped free at the last possible moment. He later learns that Petroff (Robert Kortman) has trapped the Vigilantes in an ambush at Stone Canyon and, sans disguise, enters Burr's lair to warn the megalomaniac of "The Eagle's" wrath. Assuming his disguise, "The eagle" then forces Burr (Fred Kohler) to release the Vigilantes but loses his balance in the ensuing duel. As the chapter comes to a close, Don is at the mercy of Petroff and four of his Cossacks, all with swords ready to thrust.
