Roy Rogers, le roi des cow-boys #7

In "Le sosie de Hattie Dean," Roy Rogers and his loyal companions Trigger and Bullet ride into a ranch under suspicious circumstances when Hattie Dean is mysteriously held captive. With Sheriff Jim and the local townsfolk unaware, a look-alike has taken her place, turning the ranch into a front for a network exploiting transient laborers. As the truth begins to unravel, Roy must uncover the deception before the real Hattie is lost to the shadows.

In "La grotte mystérieuse," Roy Rogers and an old prospector follow a trail of clues to a hidden cave, where they uncover both a stolen armored car loaded with over two hundred thousand dollars and a hijacked army truck. With Trigger at his side and Bullet close behind, Roy must outwit the thieves before they strike again, all while Sheriff Jim, Burro Baker, and the mysterious figures of Bering, Baltic, Channel, and Cossack watch from the shadows.
