Thanks for your kind words, muted79. I'm glad you enjoyed the Pat O'Farrell story. If I end up having half as much fun with Charlie Callahan's tale as I did with the O'Farrell saga, it will have been time very well spent.
I think it's fun to try to capture the feel of the era I'm writing about. It's challenging sometimes; I end up spending a lot of time researching the slang of an era, or finding the name of a song one of my characters might have enjoyed. Sometimes I feel like I'm doing everything BUT playing OOTP.
The fact that I'm an American history teacher makes it easier, I suppose, and it certainly makes it more enjoyable.
Thanks again, and I hope you continue to enjoy the story!
