Eggs From French Marans Hens
Each morning while at home, James Bond prefers to eat the same breakfast. As usual, Ian Fleming spares no detail in relating this specific item in From Russia With Love:
The single egg, in the dark blue egg cup with a gold ring around the top, was boiled for three and a third minutes.
It was a very fresh, speckled brown egg from French Marans hens owned by some friend of May in the country. (Bond disliked white eggs and, faddish as he was in many small things, it amused him to maintain that there was such a thing as the perfect boiled egg.)
