Persona Non Grata

by Ruth Downie

Reviewed by Margaret Donsbach

Persona Non Grata is the third mystery in the Gaius Petreius Ruso series about an army physician from Roman Gaul posted in northern Britain. Medicus, which launched the series, was a bestseller, and Persona Non Grata is a worthy successor.

A terse letter marked "urgent" has arrived from Gaul: "Come home, brother." Ruso wangles some extended leave and goes to see what the trouble is, bringing along his British mistress, Tilla (short for Darlughdacha). On arrival, he finds his presence deeply unwelcome. The near-bankrupt family estate is being claimed by a creditor held at bay only because Roman law prohibits confiscation of an estate whose owner is absent on military duty - Ruso, absent no longer. Then a man falls dead of poison while he and Ruso confer privately, and Ruso's flighty stepmother has the evidence scrubbed up before he can stop her. Who wrote the letter? No one will admit to it.

Ruso, Tilla and a cast of vividly drawn supporting characters plunge readers into an alien society while revealing passions and vulnerabilities we can still relate to. Struggling to protect his teenaged sister from an embarrassing love affair, Ruso "was silently mourning the erosion of the power of the Paterfamilias. There had been a time—he was not sure when, but he knew there had been one—when the head of a Roman household had enjoyed absolute power as well as ultimate responsibility."

Meanwhile, capable and intelligent Tilla is a fish out of water in Gaul, where everyone from Ruso's family to strangers in the street look down on her as a barbarian. Comparing herself to Ruso's gracious (and secretly unhappy) sister-in-law, she berates herself for not "loyally supporting him as if she thought he ... was the cleverest, bravest, and most interesting man in the world. That was what Roman men seemed to want."

One of the delights of Persona Non Grata is Downie's sense of humor. A scene in which a household slave brings pagan Tilla to a meeting of secret Christians is laugh-out-loud funny, while remaining warmly sympathetic to both Christians and pagans. (2009, 348 pages, including an Author's Note discussing the historical background)

Persona Non Grata is one of five mysteries on my "Best Historical Novels
I Read in 2009" list.
