Correct P_Lombard!! Lydia made the comment about her father-in-law, Simeon Lee.
"One of them took my shoes away, though I had expressly told him - by pantomime too - that I preferred to clean my shoes myself."
My quote is:
"Let’s stab him, Rhoda, and see if his ghost can come back and find out who did it."
Mrs Blair said:
Oh, I love this book. It's Cards on the Table and I think it's Major Despard?
Mrs Blair said:Is it the last line of the book too?
You are more than right, Mrs Blair. I also love this book and the ending is one of my most favourite. It is your turn now.
