The Three Investigators is an American juvenile detective book series first published as "Alfred Hitchcock and the Three Investigators". It was created by Robert Arthur Jr., who believed involving a famous person such as movie director Alfred Hitchcock would attract attention. 
 
The original series was published from 1964 to 1987 and comprised 43 finished books, one unfinished story (The Mystery of the Ghost Train) and four Find Your Fatebooks. Between 1989 and 1990 Random House published the Three Investigators Crimebusters series.
 
The characters known as the "Three Investigators" are three boys named Jupiter Jones, Peter Crenshaw and Bob Andrews.  Most of the mysteries involved investigation of baffling phenomena (e.g., an ancient Egyptian mummy that apparently whispered and a human skull that seemed to talk).
 
The Three Investigators are a junior detective team that initially came together because of a mental exercise club. They live in Rocky Beach, a fictional coastal town between Los Angeles and Santa Barbara. In some of their cases, the boys are supported by Alfred Hitchcock, the chauffeur Worthington, and the police inspectors Reynolds and Cotta. “We Investigate Anything” is The Three Investigators' trademark slogan on their business card. Most often, Jupiter is the one to hand over the card in a fitting moment to see the clients’ reactions to the three question marks. Often, that reaction is a joke, with the clients asking whether the question marks mean the investigators doubt their own abilities. Jupiter usually retorts something like: “That's our symbol. [...] The question marks stand for mysteries unsolved, riddles unanswered, puzzles of any kind. So we use it as our trademark. We investigate any kind of mystery.”
