I recently read my first Michael Connelly crime novel, "The Scarecrow." It made occasional reference to the killer in a previous Connelly novel, "The Poet." Having been immensely entertained by "The Scarecrow," I soon read "The Poet." It's also a terrific book, but the ending was partly ruined for me because I knew from reading "The Scarecrow" that "The Poet" couldn't possibly end in the way the author was leading the reader to believe. In short, by reading the books out of order, I killed some of the suspense in the second one read.
