Bruno Sinclair Bolet is Henry Bolet's late great-uncle.
Bruno was born in 1912 and became a well-respected dentist. At some point in his life, he lost one of his eyes and had to wear a glass one. Bruno collected several glass eyes and would wear a different one every day. He also kept a variety of exotic pets including an alligator, an iguana, and a large spider that would come and go as they pleased. Bruno's home had a large cemetery behind it that he took good care of; he even made a detailed scale model of it in his living room so he could better keep track of the graves. He was skilled in making such models and even won first place in Miniature Modelers of America in 1978, 1982, 1985, 1986, and 1991.
At some point, Bruno met Dr. Gilbert Buford and eventually considered him to be a close friend. Bruno was later admitted to the secretive Jolly Roger Krewe, a Mardi Gras organization that hailed Gilbert as its leader.
When Bruno's nephew Claude and his wife Marianne died in a car crash, Bruno, as their only living relative, took in their son, Henry, who was just eight years old at the time. Although Bruno did care deeply for Henry, he was at a complete loss as to how to show it- as a quiet and rather isolated man himself with very few friends, Bruno simply didn't know how to show his affection in traditional ways and ended up sending the boy away to boarding schools and even military school.
Somehow, Bruno acquired one of the legendary crystal skulls and went to great lengths to protect it, devising several puzzles within the cemetery and his house to keep it safe. He believed very much in its supposed ability to grant immortal life- which is why it came as such a shock when the authenticator he sent it to replied in a letter that the skull was a fake. In fact, the shock was so great that it induced a heart attack in the 95-year-old Bruno. It just so happened that his old friend Dr. Gilbert walked in at that moment, saw Bruno lying on the floor, and immediately went to his side, telling the panicking housekeeper Renee Amande to call an ambulance. However, Bruno knew he was dying and told Gilbert with his last breath to hide the first clue to finding the treasured crystal skull -a painting of Henry's parents- in their crypt, so that his grand-nephew Henry would be able to find it.
