A British television series from the mid/late 90s, where the protagonist is a detective (?) somehow able travel back in time a few days (perhaps a week?) to solve crimes. I think other characters were unaware of his time travels...
I remember one episode where, during his investigation in the past, he saw a colleague and slipped him a piece of paper with some lottery numbers to play. When he arrived back, the rest of the team were celebrating his win with "bubbly", it then transpired it wasn't actually "real" champagne, confused we find out that:
his colleague had put down the numbers upside-down, somehow meaning he'd got four numbers (several hundred pounds) rather than all of them (several million).
The premise sounds a lot like Seven Days, though I think this programme was aired prior to that...
Any ideas?
