"Surely your wife knew?" "No, sir. I had said nothing to my wife until I missed the papers this morning." The Premier nodded approvingly. (Second Stain.18-20)
The Premier definitely comes off as full of it here, since he "approves" of how Hope kept professional secrets from his wife, for security purposes. Granted, this was probably a good move considering he was married to Lady Hilda, but this little scene indicates how marriage was often not really a union between equals in this era, when women were generally seen as "lesser" than men.
