Sir Sam Vimes gets knocked back in time thirty years in this rollicking adventure in Terry Pratchett's bestselling Discworld(R) series

One moment Sir Sam Vimes is in his old-patrolman form, chasing a sweet-talking psychopath across the rooftops of Ankh-Morpork. The next, he's lying naked in the street, having been sent back thirty years, courtesy of a group of time-manipulating monks who won't leave well-enough alone. This Discworld is a dark place that Vimes remembers all too well--three decades before his title, fortune, beloved wife, and child on the way. Worse still, the murderer he's pursuing has been transported back with him. And on top of that--it's the eve of a fabled street rebellion that killed a few good (and not so good) men. Sam Vimes knows his duty, and by changing history he might just save some worthwhile necks--though it could cost him his own personal future. Plus there's a chance to steer a novice watchman straight and teach him a valuable thing or three about policing--an impressionable young copper named Sam Vimes.
