Ng'wagu who for years has lived in Utitu - The Land of Darkness - comes to the Jungle Hospital to see what Jungle Doctor could do for him with his instruments of iron.

Truly the Bwana has strong medicine for eyes, had said his friends. But Berenge, the witchdoctor had grown rich by his own brand of strong medicine for eyes - so strong that it meant almost certain blindness for his patients - and he is not letting Ng'wagu out of his clutches so easily.

The story tells how his evil deeds at length were thwarted, and how Ng'wagu found light, not only for his eyes, but also for his soul.

Another thrilling adventure from Paul White based in Mvumi hospital, Tanzania.
