The Mysteries of the Rosary

The Lannington Rosary, missing for 500 years, is a relic blessed with healing powers. Professor Hilary Ambrose (James Laurenson) has sent an ancient prayer book containing a clue to its whereabouts to his old friend Father Brown, before he goes missing and his home is ransacked. Brown receives unexpected help from the untrustworthy Flambeau (John Light), returned from the dead. A terminally ill fellow priest, Father Ignatius (Anton Lesser) also seeks the rosary.
