Query: Thumbs Up!!

As the reader can deduce from the title this novel is about Ancient Rome. Is is set at the time of the Emperor Constantine and his manipulative mother Helena, who is the power behind his "reign". Claudia the leading character is Helena's spy. She is heavily involved with one of the foremost gladiators in the city and he has become the subject of a heavy betting syndicate who are attempting to manipulate his fights in the arena to their advantage. The book is full of the savagery and violence that is well documented for that period of history. Paul Doherty seems to be able to turn his hand to any period of history, be it Rome, Ancient Egypt or Medieval England. This is as good as any of his recent books.
