Dozens of pets jumped off bridge at estate which is rumoured to be haunted by ghost of lonely widow?

Around 100 dogs have jumped to their deaths from the bridge at Overtoun House, near Dumbarton, Scotland (pictured above, inset), and this ghostly figure (pictured above, left circled in red) is believed to be behind the strange phenomenon.
Looking out from behind the curtains, the white figure is believed to be Lady Overtoun. Her billionaire husband built the estate and she was said to have wandered the bridge grief stricken after his death. Dog owner Alice Trevorrow (pictured above, right with Cassie) watched her dog suddenly jump over a parapet onto the stony ground below last year. She described her Springer Spaniel's behaviour as total out of character.
