Sister Boniface Mysteries dives into the endearing world of Great Slaughter and its secret weapon in its fight against crime, Sister Boniface. At a time when police forensics is rudimentary, Boniface's I.Q. of 156, her PHD in forensic science, plus an addiction to popular detective fiction and a fully equipped crime laboratory make her an invaluable aid to Police investigations. Mud, blood, stains, hairs and fibres. If there is evidence to be found Boniface will find it. Poisons, trace evidence, blood stains, etymology. She's more up to speed on the latest forensic techniques than the Police.
