[Stolen Shakespear scripts...what movie?]

I saw this on TCM about a month or so ago. It was a movie with this team or a wife and husband and the husband was a detective/book buyer? And the main item in this movie is a copy of Shakespeare Script if I remember correctly that was stolen, they think its the 'bad' son who owes money. the couple that help the cops are in a few other movies together too.

 

Please help me remember the name, I know its not available on DVD as I did look it up that day.

Thanks in advance!

I'll always purchase WS over pan and scan, I've not bought DVD's because they aren't in WS. This is how I used to buy mt VHS as well. A true film buff will always buy WS/Letterbox!
