Screwtape Letters

I am missing my copy of Screwtape Letters.

I loaned it out a number of years ago, but I cannot remember to whom it was loaned.
It was my grandfather's, so it does have some special meaning to me. It is a small paperback with dark cover art, published sometime in the 1960's I think. It was in rough shape when I loaned it out, some tape rips and such. It might have my grandfather's name in it (Sidney Dove).

Please search your bookshelves for this, I really would like to read it again.

Thanks.
