Dennis Bishop was a resident of the same orphanage as Tom Riddle (later Lord Voldemort). Amy Benson (also a resident of the orphanage) along with Dennis Bishop were taken to the cave (later home to the Horcrux locket), against their will, where Tom Riddle did something so terrible, the two would not speak of it.
Behind the scenes
- In a deleted scene from the film adaptation of Harry Potter and the Half-Blood Prince, Albus Dumbledore states that the two children taken to the cave were Tom Riddle's fellow students. This could imply that they were also students at Hogwarts, but it is more likely that Tom attended another Muggle school with them for their early education.
The name "Dennis" comes from Denys or Denis, the medieval French forms of Dionysius. Saint Denis was a 3rd-century missionary to Gaul who was beheaded in Paris. He is credited with converting the Gauls to Christianity and is considered the patron saint of France.
