Night Watch written by Terry Pratchett performed by Stephen Briggs on Cassette (Unabridged)

Commander Sam Vimes of the Ankh-Morpork City Watch is back in his own rough, tough past. He must track down a murderer, teach his young self how to be a good cop and change the outcome of a bloody rebellion. There's a problem: if he wins, he's got no wife, no child, no future.
