Rio Grande Black Magic

Johann Gunther is a German immigrant, a West Point graduate, ex-US Army officer and former Texas lawman. He fought alongside Teddy Roosevelt in the Spanish American War in 1898 and in the Great Game in Afghanistan in 1906.

Now Gunther, with the help of his life-long friend Jefe, runs Remedies Detective Agency. During a routine mission to purchase guns for a security job, Gunther, Jefe, and the Whittle boys head to Tremboro, Texas, near the Rio Grande. In Tremboro their paths collide with Pancho Villa and his band of revolutionaries who are in town to recruit mercenaries. As events unfold, Gunther discovers Villa's plans to steal much-needed guns and supplies. Villa is angry about the American Government's rejection of him and has revenge on his mind. In Tremboro, with his activites cloaked by the Day of the Dead Celebration, Villa and his band of outlaws and misfits threaten, blackmail, rape, shoot, and steal. They plan to take whatever they want and leave a wave of destruction and dead bodies behind.

It's up to Gunther to stop Villa and save Tremboro. But to stop Villa, Gunther must uncover and then foil his plans. Gunther battles Santa Muerte witches and their magic, revolutionaries, and mercenaries to save the innocent citizens of Tremboro. Can he stop Villa and save the town? Or will he fail? Will his efforts label him as Villa's assassin decades later?
