The Fabulous Valley

John Thomas Long was dead. And to his heirs he had left a tantalising, half-hope of riches. A cache of diamonds, somewhere in a leopard-guarded valley in in the Kalahari desert. Their clues were few and strange enough: a knobkerrie, a string of monkey skulls and a leopard skin. Probably they would never have set out if they had known of the dangers, the terrors that lay in wait for them.
