Outers, in the first story he is 13 years old. His birthday falls between Christmas and Easter. Margaret "Daisy" Daykin – Larry's younger sister. Creating the Five Find-Outers was Daisy's idea. She is particularly good at thinking of plans and ideas. She is younger than Larry by a year and the same age as Pip and Fatty, who are 12 as the series begins. Philip "Pip" Hilton – The same age as Daisy and a few years older than Bets, his younger sister whom he frequently teases. In contrast to Fatty's rather relaxed parents, Mr and Mrs Hilton are quite strict and often take a dim view of Pip and Bets's sleuthing activities, wishing that Pip especially would direct the same amount of energy into his schoolwork. In The Mystery of the Hidden House the Hiltons forbid Pip and Bets from getting involved in mysteries, but the children still find themselves in one. He is 12 at the beginning of the series, nearly 4 years older than his little sister. In later stories we learn that Pip's birthday falls early in January, while Bets' falls during the Autumn term.

She is keenly observant, providing crucial ideas that help Fatty in solving some of the baffling mysteries - as in the 'Mystery of the Pantomime Cat' when she provides the breakthrough idea, to which Fatty exclaims: "Bets!

She also thought of the name 'Five Find-Outers and Dog'. She is by far the youngest of the five, beginning the series at just 8 years of age, but is then the first to have a birthday- in the Autumn term between the 2nd and 3rd books of the series. Buster – Fatty's jet-black Scottish Terrier. He thinks the world of Fatty and his favourite pastime is to nip at Mr Goon's ankles. His favourite food is biscuits, spread with potted meat. Originally Larry, Pip, and Daisy only let Fatty join the detective club because of Buster. Police Force Theophilus Goon, the village policeman and Ern's uncle, who
