What Time Does Edinburgh's One O'Clock Gun Fire? is a charming book mixing the rich history of the One O'Clock Gun with a bountiful selection of amusing Castle anecdotes. The firing of the One O'Clock Gun has been a recognised custom in Edinburgh since 1861, startling millions of visitors to Scotland's capital. The time gun is fired daily from the Mills Mount Battery of Edinburgh Castle at 1300 hours precisely, except on Sundays, Christmas Day and Good Friday.

Nearly as famous as the One O'Clock Gun is the man who fired it for over 25 years: District Gunner Tom McKay MBE (aka "Tam the Gun"). Until his death in 2005, Tam served as an ambassador for Edinburgh, the Castle and its famous Gun. He made friends from all over the world with his irrepressible personality as he conducted his ceremonial duty every day, and in his frequent public engagements to promote the Gun and Castle as major attractions in Edinburgh.

For anyone not lucky enough to have met this most beguiling of Scottish treasures, or simply seeking a memento of his much-missed wit and wisdom, this book will not disappoint.
