Episode #2.7 - S2-E7
Other mistake: When the dowager visits Matthew in his bedroom to tell him Mary is still in love with him before he goes through with marrying Lavinia, the curtains hanging behind Matthew are so wrinkled and creased just as curtains are when they come out of a package from the store. The crease lines are terrible! One would think set design would have steamed them as in real life, they would have been custom-made and certainly not folded up like that for shipping, thus never having creases like that.
Answer: The letter was addressed to Edith, an adult woman. As such, the family respects her privacy and would not question her receiving something from her own doctor. If anyone asked, she would merely give some vague explanation for seeing a physician. If she was concerned about anyone becoming suspicious, then she could have instructed the doctor's office to send it in a plain envelope.
