WOMAN IS FOUND DEAD IN THIS APARTMENT. EXAMINE THE CRIME SCENE!

This is a photograph of an actual bedroom where woman is found dead. At first glance, the faded 1903 photograph of this bedroom shows what looks to be an unremarkable middle-class Parisian apartment of the time. The overstuffed room brims with floral decoration, from the wallpaper and heavy swag curtains to the carpeting. But on closer look, there is something unnerving about this photo. Find the clues to continue the investigation, and deliver evidence to the police chief. 

If you have found evidence that crime has happened, to go further insert evidences in this order:

evidence1–evidence2–evidence3

Use small caps throughout the game. When typing pasword, instead of space bar use –
