Swift delivery and a decent price. "Gateway to Hell" is the weaker of the 3 books and frankly not really a "best of". I hadn't read it for many years so it was still worth the read. I hadn't read "To the Devil a Daughter" before having seen the pretty poor "Hammer" film and not realising that it was so loosley based on the book. Thoroughly enjoyed it and wished the film had stuck to the original story. It would have been so much better.
Finally "The Devil Rides Out" was a nostalgic trip with DW at his best. Allow yourself to be transported back to the mid 20th century and accept the differences in attitude of the characters to that of modern day. You won't be dissapointed.
