The Eye of Apollo : Father Brown

The tenth story in The Innocence of Father Brown is entitled "The Eye of Apollo." At the beginning of this short story, Flambeau has just opened his detective agency in a new building located near Westminster Abbey. The other tenants in the building are a religious charlatan named Kalon, who claims to be "the New Priest of Apollo," and two sisters, who are typists. Flambeau and Father Brown instinctively distrust Kalon, who has installed a huge eye of Apollo outside his office.
