Diamond Safari

In Johannesburg, South Africa, adventurer Harry Jordan is asked by a native medicine man to help a young woman from Zululand whose husband, Stephen Timbu, has been accused of murdering a fellow gold miner in a drunken rage. When Harry goes to the police headquarters to examine the case records, Sgt. van der Cliffe shows him an enraged Timbu and his badly beaten cellmate. The evidence suggests that Timbu is guilty so Harry advises his wife to return home as there is nothing he can do. Later, Harry encounters Jan Reubens, an investigator for mining syndicates, who tells him that it is important for his current client to establish Timbu's innocence or guilt.

Reubens then sends Harry to Rhodesia to investigate Williamson, whom he meets by feigning an automobile breakdown.

Williamson, who has been drinking heavily, has killed many lions, but fears this one, as he believes that it has supernatural powers and is trying to avenge the deaths of the other lions. When Harry and Williamson go to track the lion, Williamson becomes fearful, prompting Harry to tell him that the lion will follow him the rest of his life unless he faces it now.
