Chesterton propounds the thesis that "those who say that Christ stands side by side with similar myths, and his religion side by side with similar religions, are only repeating a very stale formula contradicted by a very striking fact." And with all the brilliance and devastating irony, so characteristic of his best writing, Chesterton gleefully and tempestuously tears to shreds that "very stale formula" and triumphantly proclaims in vivid language the glory and unanswerable logic of that very striking fact. Here is the genius of Chesterton at its delightful best.
Short story “The Blue Cross” is Chesterton's first Father Brown mystery.
It introduces the characters Flambeau and Valentin. It is unique among the Father Brown mysteries in that it does not follow the actions of the Father himself, but rather those of Valentin.
Brown has been committing acts to draw the attention of the police (throwing soup, knocking over apples, smashing a window) and leaving an obvious trail for them to follow. Valentin takes this opportunity to emerge from hiding with the policemen and arrest Flambeau. Both Flambeau and Valentin bow to Father Brown's superior detective skills.
