Doctor Gaius Petreius Ruso has arrived back in Britannia with his new wife Tilla and a trunk full of wedding crockery. His friend and colleague Valens has promised to help him find work, so while Tilla yearns for somewhere to make a home, Ruso is tasked with hunting down missing tax man Julius Asper.

Of course there’s something else missing: money. And the Council of the town of Verulamium is bickering over what’s become of it. Compelled to delve deeper when Asper is found murdered, Ruso discovers that the good townsfolk may not be as loyal to Rome as they claim.

Despite Ruso’s best efforts to get fired from the job of investigator, he and Tilla find themselves trapped at the heart of a treacherous conspiracy involving theft, forgery, buried treasure, and the legacy of Boudica, the rebel queen.

 

Ruso and Tilla are on their way back to Brittain after their adventure with family and murder in Gaul.  Married, but without his old job as medicus in the Roman Legion, Ruso grudgingly agrees to a job his old medicus pal, Valens, who’s gone into private practice has dug up for him- find a missing tax collector and the tax money.

Ruth Downie once again entertains and instructs her readers all in one with her wonderful descriptions of Roman Era Brittain and her colorful, bantering characters, Ruso and Tilla solving mysteries as they happen upon them- which is often, it seems.

Ruso is still a little surprised at the turn of recent events that have led to him leaving the 20th Legion, returning home all sorts of family troubles, and now escaping, erm, that is returning to find work in Brittain with Tilla as his wife, now.  A Roman with a Britain wife is mildly problematic, but being foot-loose with no prospects is the crux of his troubles.

So, when Valens recommends him as a professional investigator to the governor’s finance department in Londinium as just the man to find their missing tax collector and the tax money from a prosperous town up the road a little way, he reluctantly takes on both the false persona and the task.  Tilla already volunteered him to help the missing man’s very pregnant Iceni princess wife, anyway.

Ruso isn’t on the job long when he trips over a murder and growing evidence that this is not a straight-forward case of the man absconding with the tax money.  He’s investigating under the observation of the city council in question and the governor’s staff and someone is doing away with people who get too curious about that tax money.  Meanwhile, what is going on with Valens and his wife?  Not that he has time to consider another man’s wife when his own is an utter mystery to him already.

Caveat Emptor carries on the series story arc of Ruso and Tilla and has wonderful descriptions of a Roman era town’s workings.  I found the historical details as fascinating as ever and was highly entertained by the banter and partnering of Ruso and Tilla.  Let’s add in Ruso and Valens, too.  The series remains strong for me and I definitely recommend it to historical mystery fans.

    • This pair get me to giggling out loud and then I still get a good murder mystery and fascinating historical backdrop. 🙂

    • You said it, Mary. Ruso’s luck runs along the lines of “if I didn’t have bad luck, I wouldn’t have any luck at all” LOL, poor guy.

    • Oh man, the covers! I think each book in the series has at least three different covers and even the name of the series has three different options. More to love, I guess. Haha!
