St. Patrick's Day

It’s almost St. Patrick’s Day, but . . .
The gardener at an historic cemetery has come across strange words newly etched into a centuries-old gravestone. A real threat? Or just words to taunt the authorities?
The police ask the Krewe for help.
Because they are so close to D.C., and they can’t take chances. There are groups and individuals who will use any occasion or date to create havoc and mayhem.
Jackson and Angela usually celebrate St. Patrick’s Day with their family, both having a wee bit of the Irish in their backgrounds.
But this St. Patrick’s Day, they will be on surveillance.
They will have some unexpected help through their son, Corby . . .
And the arrival of a strange and unexpected visitor to the graveyard.
