S2·E4 Episode 4

The body of a newborn baby is unearthed in a churchyard after a priest reluctantly comes forward with information given to him in confession about a possible body buried in the local presbytery. When the priest is later found hanged in his office, the detectives' initial thoughts are suicide, but why would a priest commit a mortal sin by taking his own life? Could the two deaths be related? Meanwhile, Joe's new girlfriend, Harriet's best friend, pressures him to tell Harriet about their relationship.
