“James, this time it is serious.” Joyce noticed that her Dad paused intentionally waiting for his daughter to finish serving tea before he could respond. Joyce finished her chore and left the room. In July that year, an assassin shot and killed Tom Mboya in a Nairobi street. This air of political uncertainty continued to affect even the relations between Nyamweya and Sagini towards the end of the sixties. Members of the Nyamweya family also noticed that a sense of distrust was beginning to build up between the then Vice President Daniel arap Moi and Nyamweya. These sore relations arose from a growing speculation at the time that Nyamweya was a pretender to the Vice Presidency, as Kenyatta succession politics heated up in the seventies. J. M. Kariuki assassination After assassination of another of Kenya's leading politicians, J. M. Kariuki, Parliament appointed a Select Committee to enquire into the murder. Owing to enormous trust he commanded among parliamentarians and executive, Nyamweya was the only cabinet minister appointed to the Committee. On the day Parliament was voting whether to adopt or simply note the Report of the Select Committee, Nyamweya happened to be out of the country attending the graduation ceremony of his daughter Rebecca at St Lawrence University, Canton, New York. A major controversy arose after then Attorney General, Charles Njonjo, introduced a peculiar measure requesting Parliament only to note the Report of the Select Committee instead of adopting it. As expected, government rallied its troops in Parliament to support this position. Kenyatta later sacked two members of the executive, Muliro and John Keen, for voting with the opposition. Simeon Nyachae One of Nyamweya's best friends was the former minister and Chief Secretary, Simeon Nyachae. The two were close friends and when the latter was Provincial Commissioner in the Rift Valley and based in Nakuru, Nyamweya and family never missed an opportunity to make a stopover for a meal before proceeding on to Nairobi or Kisii. Somehow, by the time Nyachae was moving to Nyeri as PC Central Province, a rift had started to emerge between the two. However, while Nyachae was Chief Secretary, the two managed to hold a couple of meetings culminating in restoration their friendship. President Banda Another great friend of Nyamweya was the then President of Malawi, Dr. Kamuzu Banda, who spent a night in Nyamweya's Kisii residence when he paid a state visit to Kenya.
