Murder Britannica: Just when you thought it was safe to go for a nice bath - Paula Harmon - Bog

190 AD Pecunia: an insignificant town in west Britain. Romano-Briton Lucretia is determined that her get-rich-quick scheme will not be undermined by minor things like her husband's death, dubious imposters or her married daughter's fascination with a celebrity gladiator. But when the bodies start to mount up, wise-woman Tryssa starts to ask questions. Certain that a forgotten goddess cannot be blamed, Tryssa needs to uncover the truth before another life is lost.
