Please help I'm looking for a pc game in which i can not remember the title. Im not sure how old or new it is

From what i am pretty sure, it is about solving various mysteries around a town by looking for clues and when all the clues have been found, choosing who you think is the criminal. there was a scrap book of finished mysteries. The game had voices

From what i remember, which may be wrong, in the begining you choose whether to play as a guy or a girl, who could have been teenagers. the first mission or atleast one of them, was about some guy possibly named mark, leaving peices of paper that said "clue" on objects, which were related to his name (which as i mentioned may or may not have been mark) and telling you to find out who he is. There might also another mystery about a ghost in a theatre or museum. The objects which were clues or could be clicked on had a square around them.

Locations in the game i can remember are a bank, an arcade, and an icecream parlour

Thanks in advanced
