If you have read one in this series of novels concerning a 'snoop' in ancient Rome, at around the time Julius Caesar rose to prominence, then you have read them all ! So saying, I enjoyed this as much as the preceding 4 in the series. For those who have read the 'Falco' series these are very different: the character of the protagonist is very different (he comes from a priviledged background and is an amateur), yet like Falco he does a private life (and a public one - he is quite well known), from which the reader can learn a little of the structure of life in the republic.
To describe the plot, without, I hope, giving too much away: our hero is recalled from exile on Rhodes by his family near the feast time of Saturnalia (December), who need his investigative skills to implicate a certain person in the death of a relative. Early on he runs across his arch-enemy, who threatens him in order to clear the same person. Much of the story involves chasing (following up) female witnesses (I use the term witness loosely) around the outskirts of Rome. The identity of the killer only becomes clear near the very end of the book, and is, to my mind, a complete surprise - but I had no opinion as to which character it might be.
The paperback is very reasonably priced, and I think I purchased it direct from Amazon, and it arrived in three or four days in perfect condition.
The book is compulsive reading, and as such does not take long to read !
