I've made the mistake of watching Harper's Island on BBC 3 on Sunday nights. I'm now hooked.
Plus they show a double bill. I love watching good US shows on the BBC because you get no adverts, and it lets the tension build nicely.
Sadly this is the problem. It's quite scary and....well.... it's giving me nightmares such that my sleep patterns are completely buggered at the start of the week.
I should probably stop watching it, but I reckon I know who did it (no spoilers please) so I'll have to keep on going until the end to prove whether I'm right or not.
Just don't ask me anything complicated on a Monday morning.....
