quarry

Khalusha was the prime suspect in the murder of more than 40 women whose mutilated bodies were discovered in a disused quarry that became a dumpsite in the capital, Nairobi.

The contest is staged in a former slate quarry that was flooded by a tidal wave in 1881.

Instead of taking us inside ramshackle houses and down cold streets, we swim with Robbie and Maeve at the local quarry, their small piece of paradise, and walk through its woods.

Some of the rubbish will have to be dug up and removed because the disused quarry is not an appropriate place to store industrial waste.

The surprise was hidden deep in the historic Dinorwig Quarry, in Gwynedd - which was the world's second largest slate quarry when it was opened more than 200 years ago.
