Beginning the second book on ATG

I have been thinking about how Alexander reacted immediately after his father's death. Some people probably were suspicious that he and Olympias could have been behind the plot to murder Phillip but I am convinced that they were only aware that it was a possibility and neither had any real part in its execution. While Alexander may have felt threatened many times that his own succession could be challenged there is no reason to believe that he ever doubted for a minute that he was to be the person who would succeed his father. after all he had been regent, had led the troops in command and was very instrumental in twice saving his father's life when Phillip was under threat of death. There is no reason to believe that Alexander was so insecure at age 20, even with the threat of a new wife and child, that he would contemplate murdering his father. Nor do I think that Olympias had anything to do with it, but did show her extreme joy when it was accomplished.
