Tragedy in Heather Angel's life

Heather Angel was the doe-eyed actress who portrayed Bulldog Drummond's fiancée (and finally wife) in several movies. Tragedy struck twice in her life. Her father, Andrea Angel, was killed in the Silvertown explosion in 1917 at a plant that produced TNT. Fifty tons of the stuff exploded, killing 73 people and injuring 400 more. Angel's second husband, Robert Sinclair, was killed when protecting her from an intruder who broke into their home in 1970.
