In the car scene Mrs Pemberton mentions the name "Lillian Hall."I had to do a search and found out Lillian Hall was a silent screen actress.She was married to actor Walter Pemberton. She was also in two films directed by Hitchcock in 1927 prior to the filming of The Paragon. Hall committed suicide due to a failing career with the advent of talking movies. She slit her throat, very "Hitckcockian", whilst also using a gas oven.
Coincidence of names? Probably not.
