Yesterday, during the morning time, Chiyou received a letter from his friend Sun Mo.
The letter contained all the information about the lead Sun Mo has got so far and there was something else also written in the letter.
In the letter-
"Friend Chiyou, I found a good lead in my father's death case
It is as I expected it to be, it was not a suicide but a murder and he was killed using a certain type of poison that works really slow so there is hardly any trail or mark left behind that could be seen by others, but still I did remember about a certain purple mark on my father's neck area that helped me come to this conclusion that it was truly a murder.
I also sent military in those ministers house who were against my idea of coup but so far I found nothing.
