Rachel Verinder - Rachel is seemingly the centerpiece of mystery of the Moonstone, as the plot of the novel thickens when the diamond is stolen from her possession. Rachel is an uncharacteristic woman for her time-she goes against traditional Victorian conventions, as her dark features and small stature emit through the pages. However, she still attracts two potential suitors in Franklin Blake and Godfrey Ablewhite. Rachel is prone to temper tantrums and likes to avoid uncomfortable situations.
Franklin Blake - Franklin Blake is the editor of the collected narratives throughout the novel. It was his decision to ask every house guest their whereabouts and knowledge about the disappearance of the Moonstone. Franklin is loved by the entire Verinder household, especially Gabriel Betteredge. Franklin is well-traveled and considered handsome.
Lady Verinder - Lady Verinder is the head of a massive house in Yorkshire. She is known for her honesty and fair dealings. She is known to have had a falling out with her brother, John Herncastle, the original Moonstone thief.
Ezra Jennings - Ezra is the assistant to Mr. Candy, the doctor to Lady Verinder. Ezra is very smart and formulaic in his decision making. He’s deceptively mature-looking for his age, and is known for his height. Ezra, an aspiring doctor and researcher, has been falsely accused of wrong-doings in the past, which results in his loneliness and ostracization.
Gabriel Betteredge - Betteredge is the house steward of Lady Verinder. His whitty, comical narratives begin the novel, as his infatuation with detective work, Robinson Crusoe, and writing shines through. He is extremely close to every individual in the family, be it household servants or the blood line. As an older man, Betteredge’s sense of humor is well-liked and recognized.
Godfrey is the well-known leader of charity groups in the London area; he’s also the cousin of Rachel. He’s a respected man, known for his good looks, religious mindset, education, and financial standing.
Sergeant Cuff - Cuff is a famous detective from London and is hired to investigate the case of the missing Moonstone. He doesn't look the part of a detective, but his knowledge and persistent questioning prove impressive. He is an extremely professional man who is, by far, the best investigator for solving this mystery.
Miss Clack - Like Godfrey Ablewhite, Miss Clack (niece to Lady Verinder) makes herself out to be a savior of the evil characters who do not practice the Christian faith. She tries to “save” characters by dispensing her Christian pamphlets to them. She makes donations to Godfrey Ablewhite's charities and argues frequently with Mr Bruff.
Rosanna Spearman - Rosanna is the housemaid to Lady Verinder’s estate and a former thief. She is a quiet woman and is kind to those in the household. She begins to act oddly around Franklin Blake, which fails to go unnoticed by Betteredge and his daughter.
Mr Bruff - Mr Bruff is the Verinder’s longtime lawyer. Unlike Ezra Jennings, Bruff handles his reasoning for the mystery with very precise, logical tactics. He uses no imagination when uncovering facts. He also holds high esteem for the Indians.
Mr Candy - Mr Candy, Lady Verinder’s doctor, is extremely flamboyant in his pride for his profession. Sadly, Mr Candy isn’t of much help throughout the novel, as he’s exposed to rain, which causes him to fall ill. This leads to permanent forgetfulness and confusion. .
Superintendent Seegrave - Seegrave is another police detective, and he suspects that the servants are to be blamed for the disappearance of the Moonstone. He uses very common methods in his investigation, and it quickly becomes clear that he is terrible at his job. Yet, he’s self-assured that he is, in fact, handling the case the correct way.
Colonel John Herncastle - John Herncastle is the initial thief of the Moonstone, as he steals the gem from the Indians during an English attack. He ostracizes himself from the rest of his family and becomes bitter toward his sister, Lady Verinder.
Mr Murthwaite -Mr Murthwaite looks like and respects the Indians. His tan appearance and bilingual nature gives this away. He’s always the respected the Indians and supposes they are innocent throughout the entire investigation. He blends well into the Indian community, and then reports back his information to the English, as a kind of double agent.
