Audiobook: A Knyght Ther Was

"But the Knyght was a little less than perfect, and his horse did not have a metabolism, and his 'castle' was much more mobile - timewise! - than it had any business being!" In 2178, once time travel had become a simple task, it had also been outlawed. Those who chose to ingnore this law were known as time-thieves, and Tom Mallory was among the best of them. When he learns the precise whereabouts of the Holy Grail in 542, he sets out to obtain it with the intention of returning it to the 22nd century to make a handsome profit and to settle on Get-Rich-Quick Street. Off to the year 542 he travels to the castle of Carbonek where the great Knight Sir Launcelot is said to have possession of the Sangraal.
