I thought it would get too complicated if I went into how this was based on his secretary's book but I had read his own book. I imagine the same cases will appear in both. My favourite story was the young PC who stopped him one night and wanted him to open the suspicious box he was carrying. Eventually the PC wouldn't take no for an answer and he had to open it. Inside was a severed head he was taking home to work on. PC nearly passed out while Simpson said " I told you not to make me open it"
Forgetting where you left your keys does not mean you are “losing it”
