Status: Deceased - shot by James Bond
Actor: Anthony Dawson
Dent is seen playing cards with John Strangways and others.
When Bond arrives in Jamaica to investigate Strangways' disappearance, he questions Dent. Later, in Strangways' office Bond discovers a receipt from Dent's practice. He interviews Dent, who says he studied some rocks brought in by Strangways, but they were uninteresting and he threw them out. He also tells Bond that they were definitely not from the island of Crab Key.
Suspicious, Bond later tests Quarrel's boat for traces of radiation using the geiger counter he requested earlier. He notices that there are abnormally high levels of radiation where Strangways had loaded the rocks, which signals to Bond that Dent is a liar. At the same time, Dent meets on Crab Key with Dr. Julius No, who informs him that if Bond reaches the island he would be held responsible. He is given a tarantula to murder Bond.
During the night, Bond is awoken by the spider and narrowly escapes death. The next day in Taro's apartment, Bond waits for his would-be-assassin. Dent opens the door and shoots the decoy Bond arranged in the bed. Bond surprises him and has him drop his gun. As he clarifies some details, Dent slowly reaches for his pistol, eventually snatching it from the floor and pulling the trigger. He's out of bullets. Bond casually remarks "That's a Smith and Wesson. And you've had your six."
Bond coldly shoots him. As he lies on the floor, he shoots him again.
