The Lockwoods of Clonakilty

Bearing wounds from the Battle of Waterloo, Lieutenant James Lockwood returns to Ireland seeking the refuge of home, his wife, and their five children. But the joy of their reunion is short-lived. As an Anglo-Irish family they find themselves caught in the sectarian strife that plagues their country. And they continue to be haunted by a twisted madman, Captain Charles Barr of the regiment, who possesses knowledge of a secret that could ruin them.
As Barr’s sanity slips away, he betrays the Lockwoods, and James is ordered to leave Ireland. Before sailing for India, the Lockwoods allow their daughter Cissy to remain at home to care for their dying housekeeper. Cissy soon discovers that she is being stalked by a man who intends her great harm. She is determined to face the threat—but has few allies she can count on.
Set against the sweeping backdrop of foreign wars and a country violently divided against itself, The Lockwoods of Clonakilty tells the story of a family that must rely on cunning, courage, and—above all—love in order to survive.
Reviews
"Straddling the English and Irish worlds separated by class and culture, Lieutenant Lockwood lived a mixed bag of blessings and curses. A loving, loyal wife, an honorable but near fatal wound from Waterloo, money problems, family problems, a drug addiction and --oh, yes-- a syphilitic madman out for his blood."
