I guess I'm lucky because this was my first Deborah Crombie novel, so I couldn't compare it to earlier "better" works as I read it. I enjoyed it so much, however, I checked out all the other Crombie novels from the library and read them. I can see a definite progession in her writing (not the story line between the two detectives but actual improvement in her ability to develop her characters.) She seems to write more and more satisfying novels as she goes along.
While I read "Kissed a Sad Goodbye" I pulled out one of my maps of London, and followed the trail. This may have helped me enjoy it. I like to follow maps while I read if the author is naming and describing places. I also may have enjoyed the book more because I was in the Docklands in last fall, and walked the tunnel under the Thames to Greenwich and through the little village itself. I had wanted to see the tunnel since I read P.D. James novel "Original Sin". Mudchute was also featured in "Playing for the Ashes" written by Elizabeth George, and I think the area was captured in the film "Career Girls" too.
Also, I am an inveterate tea drinker and fan, so I loved the description of the tea business.
