The Adventures of Mabel is a children's fantasy novel by Harry Thurston Peck, first published in 1897 under the pseudonym Rafford Pyke.

The story is about Mabel, a five-year-old girl who helps the King of all the lizards and is rewarded with the ability to converse with animals.

The first edition was published in 1897 by Dodd, Mead & Co. under the pseudonym "Rafford Pyke" with illustrations by Melanie Elisabeth Norton.

[1][2] At the time, Peck was the editor of The Bookman, a literary journal which published an effusive review of The Adventures of Mabel in December 1897 under the byline Nicholas Brown,[3] and had previously published an article under Peck's name announcing the book's release by "Pyke".

[5] When The Adventures of Mabel was mentioned in the episode "Mabel" of the television show Better Call Saul as a childhood book beloved by protagonist Jimmy McGill, commentators noted parallels between Peck's and McGill's uses of pseudonyms, and compared the development of McGill's plot arc to the real-life fate of Peck,[5][6] who committed suicide in 1914 after being cut off by literary colleagues in the fallout from an alleged love affair.
