Latoni (Also known as Deter Latoni in the novelisation) was a Brazilian. He imprisoned George Cranleigh in a bedroom at the request of Lady Cranleigh to prevent the world from learning of George's condition. As friend of the family, Latoni stayed in the Cranleigh's house as George's guardian and Lady Cranleigh's informant on what George needed or wanted. He was killed by George once his insanity drove him to wanting to escape and elope with Ann. (TV: Black Orchid)
