But did Mrs Ouko have had further cause for concern?
Troon discovered that just before he was murdered Dr Ouko was changing his will, and was attempting to buy 153 acres of land bordering his farm in Koru.
Both were being handled by Ouko’s lawyer, George Oraro, whom Ouko had visited the day after his return from Washington to discuss the matter.
Ouko’s mistress Herrine Ogembo told Troon that she too had heard of Ouko’s plans when she received a phone call from an unknown woman 10 days before the minister disappeared.
The woman told her that Ouko was purchasing a farm or a business and wanted to put it in her name but his wife Christobel did not like it and had visited a witch doctor asking him to kill Ogembo and her daughter Tracy.
