The Archbishop in Andalusia by Andrew Greeley.
A mystery novel featuring the bumbling goodhearted Blackie Ryan. First time a read a novel with Blackie as the protagonist he was a Priest. Now we meet him as co-adjutor archbishop of Chicago (with rights of succession no less!)
I love the way Greeley builds his characters and how he weaves theology into the story. If I could be half the pastor, theologian and philosopher of John Blackwood Ryan I would be very happy (I''ll pass on the murder mysteries though).
