The Eye of Apollo

In "The Eye of Apollo," the tenth story of The Innocence of Father Brown, Flambeau has launched a new detective agency near Westminster Abbey, settling into a building with an eccentric religious charlatan named Kalon, who presents himself as "the New Priest of Apollo." Alongside him are two typist sisters. Both Flambeau and Father Brown feel a deep-seated mistrust towards Kalon, especially with the imposing Eye of Apollo that dominates his office.
