. >> i'm going to ask you, the comanche and the story of quanah parker and indians in texas is just such a great story generally, it's one that we all grow up hearing, we see on movies, television, we read books about it. my sense is every book has an occasion, and so what was it for you to write this particular history at this particular time? >> um, it's a good question. about 12 years ago i read a wonderful book by walter prescott webb called "the great plains." and even though it was about the great plains, it was really about texas mostly. and inside this book there was a chapter or even a subchapter about the comanches, and it put forth this premise that there was this enormous force sitting in the middle of the continent that determined how everything happened. and i'm a yankee. i'm going, what? wait a second. i mean, i might know a pequot or the odd algonquin, but i didn't know comanches at all. comanches that are something in john wayne movies was code for, uh-oh. [laughter] oh, we're in trouble now, that's a comanche arrow. so what happened was that's what set off my interest.
