Death in the Ashes: A Fourth Case from the Notebooks of Pliny the Younger by Albert A. Bell, Jr. (historical mystery)

This is a great series for those who love mysteries and those who love Roman history.  I'm both, and I'm impressed by Bell's ability to comment on Roman life in a non-intrusive way.  I've reviewed others in the series before, and this book is seriously good.  I read the book quickly because it was so much fun.
