by Gilbert Chesterton (1905). Six short stories set in the same milieu and style – but more dated – as his more famous Father Brown stories. Each is a little jewel. Chesterton’s mis-en-scene is his strong suite “We were walking along a lonely terrace in Brompton together. The street was full of that bright blue twilight which comes about half-past eight in summer, and which seems for the moment to be not so much a coming of darkness as the turning on of a new azure illuminator, as if the earth were lit suddenly by a sapphire sun. In the cool blue the lemon tint of the lamps had already begun to flame. ” N.B. A question to the color scientist – could this correspond to dusk when the three cone photoreceptor types are still operating while rods are emerging from saturating, effectively amounting to tetra-chromacy?.
