Tim Walker is an independent author based in the UK.

In 2024 Tim published his second audiobook, London Tales, to add to 2023's Thames Valley Tales. These two audiobooks were produced and narrated by British actor and author, Richard James and are available on Amazon Audible. London Tales is a collection of eleven stories that echo London's past, reflect the present and imagine its future. London Tales is a companion volume to Thames Valley Tales, re-published as a second edition in 2023. Thames Valley Tales is a collection of contemporary stories that draw on current affairs and the rich history associated with England's longest river wholly within the country.

His most recent novel is a thrilling dual timeline, Guardians at the Wall, published in June 2021. Inspired by a visit to Hadrian's Wall in 2020, it tells the story of a team of archaeologists who uncover artefacts that connect them to the life of a Roman centurion who had guarded the wall in second century Roman Britannia. The story of centurion Gaius Atticianus of the VI Legion is told in alternating chapters, shadowing the efforts of student archaeologist, Noah Jessop, to piece together an account of Gaius's life and struggles for his thesis. How close will Noah's assumptions be to Gaius's real fate?

Tim published three books in 2020 - Perverse (April); Arthur Rex Brittonum (June) and Charly in Space (September).

Arthur, Rex Brittonum, a re-imagining of the King Arthur story, is book five in his historical series, A Light in the Dark Ages, and follows on from 2019's Arthur Dux Bellorum. Book one in the series is Abandoned (second edition 2018), followed by Ambrosius: Last of the Romans (2017); and book three is Uther's Destiny (2018). Series book covers are designed by Canadian graphic artist, Cathy Walker. The series connects the end of Roman Britain to elements of the Arthurian legend, presenting an imagined history (inspired by early historical sources) of Britain in the early Medieval period, once called the Dark Ages.

Tim lives near Windsor - close to the River Thames - the inspiration for his first book of short stories, Thames Valley Tales (2015, revised second edition, 2023). In September 2017 he published a second book of short stories, Postcards from London (unpublished in August 2023 to make way for London Tales, 2023). These stories draw on the local history and current affairs of towns and cities along the course of the Thames where the author has lived and worked. A new collection of poems and short fiction, Perverse, was published in April 2020.

His first novel was a political thriller, Devil Gate Dawn, that received pre-publication exposure on the Kindle Scout programme in March/April 2016. It found a wide readership due to its unnerving predictions of a post-Brexit Britain beset by political turmoil under King Charles III's rule and buckling under attacks from terrorist groups and includes a chapter that anticipated life in Trump America, written a year before his election.

In early 2017 he published his first children's book, co-authored with his daughter, Cathy - The Adventures of Charly Holmes. Another adventure story was published in 2018 - Charly & The Superheroes, followed by Charly in Space (2020).
