On sabbatical from the Franciscan order, Father Paolo Baldi is working as a philosophy lecturer in Dublin when his life takes an unexpected turn and he finds himself helping the police to solve crimes. In Prodigal Son, DI Tina Mahon asks Baldi for his help as a translator after an Italian chip shop owner is attacked. Something the old man says sparks Baldi's interest, and as he finds out more about the Parletti family, he realises that the police have arrested the wrong person... Keepers of the Flame sees the accidental sleuth caught up in solving the murder of a leading academic. Professor Allen had been due to give a lecture on Jack Matthews, one of Ireland's most cherished literary figures, but when the body is found, the text of the lecture is missing. Could Allen's death be connected to what he was about to reveal? It is up to Baldi and DI Mahon to find out... 'Paolo Baldi... has become something of a Radio 4 institution.' - Independent.
