Based on a novel by Arthur C. Clarke, and was first broadcast on BBC Radio 4 in 1981.
Following a moonquake, the tourist-cruiser 'Selene' sinks fifteen metres into the dust of the Sea of Thirst. That dust is more liquid than sand, and it flows quicker than syrup and slower than water. No rescue attempt under such extraordinary conditions has ever been mounted - but now the lives of dozens of people are dependent upon it. Barry Foster, James Aubrey and Harry Towb are amongst the cast in this gripping, full-cast radio drama.
