William Henry Blore is one of ten people summoned to Indian Island by Lawrence Wargrave in Agatha Christie's novel 'And Then There Were None,' who have committed murder in a way that the law cannot prove or punish them for. He is a retired police inspector and now private investigator, lured to the island under the pretext of protecting his hostess. It is revealed that as a police inspector, he was bribed by a criminal gang to frame an innocent man, James Stephen Landor, for bank robbery as a scapegoat. Landor was convicted on Blore's evidence, and later died in the prison, while Blore was promoted for his testimony.
On Indian Island, he is part of the group of killers whose guilt is the greatest, and are chosen by Wargrave to die last after going through a period of suspense, suspicion, and mental anguish. This is partly subjective on Wargrave's part, since he holds corrupt policemen as a personal offense. Blore is killed as he tries to enter the house when Wargrave drops a large marble clock, shaped like a bear, onto Blore's head, crushing his skull, corresponding with the 'Ten Little Indians' rhyme, "A big bear hugged one and then there were two."
