Li-Wang’s hawks strike at the commands of the falconer Koo, spreading death in Washington! Tex and Carson get rid of the birds of prey with revolver shots and pursue Koo on the rooftops, making him crash to the pavement. A note found in the dead man’s pocket leads the pards to Li-Wangs Chinese goods store, cover for a sinister aviary. There the rangers beat up the shady oriental with their fists and use him as bait to trap the attorney Rafferty, hanger-on of Senator Russel, the black soul of the railroad speculation in Arizona.
