This is the shocking untold story of what happened after the Titanic sank. As the White Star liner went down, 1,500 men, women and children were thrown into the ice-cold water of the North Atlantic. Half an hour later they were all dead. More than a thousand of them were never seen again.

Jock and Mary. One of those who died was my grandfather Jock Hume, a violinist in the ship's band. Jock thought the job on the Titanic was his lucky break. He was 21 years old and planned to marry his pregnant fiance Mary Costin when he returned. His death sparked a long and bitter battle between the two families.

Two weeks after the ship went down, Jock's father Andrew Hume, a music teacher in Dumfries, received a bill for his son's uniform. When he asked if his son's body could be returned, he was told 'normal cargo rates would apply'. Andrew became a broken man bent on avenging his son's death.

The Titanic Cemetery in Halifax. Jock's body was one of the few recovered, along with that of the American millionaire Col J.J. Astor. A cable-laying ship brought the bodies back to Halifax, Nova Scotia, enforcing the class system as ruthlessly in death as in life. Jock is buried in Fairview Lawn Cemetery with 120 other Titanic dead.
