Query: Sherlock Holmes: the Complete Collection

I purchased this item at Amazon for my Kindle. The text started out fine, but later on was filled with misspellings, typos, etc. Also, it was NOT a complete collection. Only two of the 12 "Casebook of Sherlock Holmes" stories were included! I wish there was some way the items could be better-screened so purchases could be made on an informed basis. Oh, well, caveat emptor!
