Thanks for the replies everyone and I do hope Amazon or some other channel more visionary than the BBC picks this one up, as it was an utterly riveting first series.
Sadly, the BBC would rather broadcast dross about someone baking a cake or washed-up celebs trying to dance these days.
If TLATD does get a second series, I can see that iPad featuring as a link between the centuries, much like the BBC micro in the "Vertical Plane" incident. Whether that has been proved a hoax or not, it's still compelling stuff!
