Hi, I am looking for a mystery game/puzzle. I hope you can help guide my search. I think the category would be called "mystery puzzle kit". In the mid 1980's I bought a reproduction mystery puzzle from a national bookstore chain retailer. It might have been B. Dalton. The puzzle was a reproduction of a paper folio mystery game or puzzle from the 1920's or 1930's. It was about 1" thick and contained "clues" such as documents, letters and newspaper clippings. The object of the game/puzzle was to study the clues and build a theory of how the crime was committed (whodunit). In the back was a sealed envelope with the solution. I loaned this out in 1986 and never got it back! Please advise if you have ever seen an item like this and advise how best to search for it. Thanks in advance,

Robert
