A to Z Mysteries is a popular series of mysteries for children, written by Ron Roy, illustrated by John Steven Gurney, and published by Random House. The series is generally considered among the best "easy readers" for young children.^[1][2] There are twenty-six books in the original series; one for each letter of the alphabet. The series begins with The Absent Author (1997) and ends with The Zombie Zone (2005).

The books follow the adventures of three child detectives, Donald David "Dink" Duncan, Josh Pinto, and Ruth Rose Hathaway. They are nine years old and live in Green Lawn, a fictional town in Connecticut and they become friends.

Other characters include Pal, a dog who once belonged to criminals and now lives with Josh; Wallis Wallace, a mystery writer and sometime participant; and Mr. Linkletter, the local hotel receptionist. Others include Officer Fallon, Josh's younger twin brothers Bradley and Brian, Ruth Rose's younger brother Nate, and Mr. Pasky, owner of the local bookstore in Green Lawn.

The success of the original series inspired a follow-up series called A to Z Mysteries Super Edition with the same characters. The first book in this series, Detective Camp, was published in May 2006. In addition, Roy and Gurney created a spin-off series titled Calendar Mysteries, beginning with "January Joker" on December 22, 2009.

An article in The Horn Book Magazine states that one reason for the series' popularity may be that the main characters "are about as cool as oatmeal", offering relief to readers who may feel burdened by peer pressure.^[3]

• A to Z Mysteries (26 volumes)^[4][5]

The Absent Author was written in 1997, and is the first book in the A to Z Mysteries series. In the first installment, the Absent Author, we meet the young team: the well read and thoughtful Dink (that's Donald David Duncan); neighbor Ruth Rose; and best friend Josh. The plot involves three amateur detectives Dink, Josh, and Ruth Rose who come across a mystery when they begin to suspect that a famous mystery writer named Wallis Wallace was kidnapped when he did not show up for a book-signing.

The Canary Caper, the third book in the series, was written in 1998. The plot follows Dink, Josh, and Ruth Rose investigating a series of animal thefts. However, not long after the theft occurs, the animals are returned and all is peaceful. Until the pet owners houses are robbed the very night the pets are returned. This makes the trio look for a connection and eventually leads to a stakeout at a proposed victim's house.

The Deadly Dungeon, the fourth book in the series, was written in 1998. The trio heads up to Wallis Wallace's castle in Maine where they begin to hear strange noises in the night. While Wallis Wallace says that it is the ghost of a famous movie star who lived there years back, Dink, Josh, and Ruth Rose believe otherwise and are determined to find out the truth. When they find big footprints, Dink and Josh believe it is Wallis' brother, as his feet are about the same size as the footprints. However, Ruth Rose insists it wasn't him, as the trio gets trapped and they know Wallis's brother couldn't do that. At the end, they trap the real culprit.

The Empty Envelope, the fifth book in the series, was written in 1998. Donald David "Dink" Duncan gets several letters in the mailbox addressed to "D. Duncan".... but finds when opening them that they all start with "Dear Doris" and are not meant for him. While his friends Josh Pinto and Ruth Rose Hathaway think it is someone's idea of a joke, Dink suspects that there is more to it than that. His suspicions are practically confirmed when Doris Duncan herself shows up one day to acquire the letters and demands them immediately. Not knowing that Ruth Rose's little brother Nate took the letters unaware that they were something important, Dink apologizes to Ms. Duncan, who then leaves in an unpleasant mood. Dink and his friends investigate the letters, uncover a code in the wording, and find a valuable stamp concealed in one of the envelopes hidden under a worthless stamp. Then the owner of the valuable stamp comes to get it back.

The Falcon's Feathers, the sixth book in the series, was written in 1998. In the book, Josh discovers a falcons’ nest, he checks on the young birds every day. But when he tries to show Dink and Ruth Rose, the nest is empty! When they found a baby falcon's wing trimmed, they know that someone is stealing the falcons from Green Lawn. Now they have to find them before it is to late.

The Goose's Gold is the seventh book in the series. In the book, Dink, Josh, and Ruth Rose are visiting the Florida Keys. Two divers have found sunken treasure, and are taking donations to fund a dive to recover it. They promise to share the wealth with the community, but it all seems too good to be true.

The Haunted Hotel is the eighth book in the series. In the book, strange sounds and stranger sights are scaring guests away from the Shangri-la Hotel and out of Green Lawn. It's up to Dink, Josh, and Ruth Rose to stop the spook before their towns turn to a ghost town.

The Invisible Island is the ninth book in the series. In the book, Dink, Josh, and Ruth Rose go to Squall Island. The discovery of a hundred dollar bill in the sand prompts them to return the following day, but when they go back, the island is gone.

The A to Z Mysteries have also led to a spinoff series called Calendar Mysteries, starting with January Joker. The series is aimed at second and third graders and focuses on Dink's cousin Lucy, Josh's younger twin brothers Brian and Bradley, and Ruth Rose's younger brother Nate. The main characters from A to Z Mysteries also make occasional appearances. While A to Z Mysteries focused on alliterating the alphabet to book titles, Calendar Mysteries relates the titles and themes to the different months of the year. The time and settings of each book often correspond to various holidays in a given month.
