Query: A Dated Book

I had great difficulty finishing this book. I thought that the writing style was terrible & the plot silly. True, the story takes place & was written in the late sixties so the writing might be dated. If so, the book is far from a classic. I think the book was made into a lackluster movie too. I'm beginning to wonder about the quality of the author's other books. I've thoroughly enjoyed the movies "Ice Station Zebra" & "Where Eagles Dare" (a real favorite of mine) but I think now that I'll pass on the book versions.
