Query: Good If You Have Insomnia

This book is unbelievably slow with a convoluted plot that meanders without purpose for huge stretches. The author spends so much time on unimportant details, whipping around names and places that she misses the entire essence and feel of the old Roman Empire. For a murder mystery there is no sense of urgency or tension, just slow, boring, plodding to the end.
