Larry Norman and G.K. Chesterton
Dale Ahlquist, founder of the American Chesterton Society and acting czar of the Twin Cities Chesterton Society, offers this 2005 interview with LN regarding GKC and other matters contemporary Christian. Troubled soul and controversial though he was, Norman is intellectually impressive and quite perceptive about the state of things in popular Christianity in this Gilbert Magazine piece. Regarding Father Brown (GKC's detective protagonist):

...But when I began reading the Father Brown volume, I realized that nothing is more natural than a Christian doing detective work.
GM: How’s that?
LN: Because that’s what each of us is called to do; to search the scriptures, and test the spirit, and follow the light. In essence, to become a converted believer is a miracle beyond our intention. But to carry on from the cross and find out what it means to be a Christian requires that we sleuth our way through the misdirection of modern religious culture and uncover the crimes of our own heart and amass the evidence against ourselves so that we can throw ourselves upon the mercy of the court, which is God’s own unconditional love. So in the end, there is no penance required for our conversion itself, though we may continue to pay the price for our previous choices.
