A few friends meet at a guesthouse. In the wake of the night, Aleph is killed by someone among them. Before Aleph breathes for the last time, he cleverly writes and mark something on his pocket calendar, careful not to write the name of the killer because he knows the killer is smart enough to get rid of any evidence.
The police arrive at the crime scene and searches for the evidence; not able to find any. Then they find a pocket calendar inside the inner pocket of the vic jacket.
Attached is the image of the pocket calendar.
Can you guess the name of the killer even though you dont know the name of the friends?
