Letter in example sentence
An average Lone Star film -- built on convenient coincidences (Gat Gann just happens to walk into the scene and dies, and, as luck would have it, just happens to bear a letter of introduction to the man, "Gantry" who, as fate would have it, just happens to have killed John "Ted" Wayne's father and for whom Ted goes to work because Ted just happens to look just like Gannon in his "Wanted" poster, etc., etc.) and clichés.
