Sherlock fans eagerly await as cliffhanger to be solved

One of television's biggest cliffhangers since "Who shot JR?" will be solved tonight when millions of Sherlock fans find out how he survived his rooftop leap at the end of Series 2.

Fans tuning in to the last series saw Benedict Cumberbatch's character appearing to lie dead on the pavement ... before resurfacing very much alive and watching over his own grave.

The show's co-creator, Mark Gatiss said, "We knew right from the start how we were going to do it.

"But we had absolutely no idea it would take on the epic proportions it has so that really by the time we came to actually do it we really had to address the fact it had become so huge and there are only so many ways you can jump off a building onto the pavement."
