Imagine in this game you are the worker of a company which deals with distributing insecticides in houses all around in your country. One day you got a phone call from an upset pensioner who complained about the conditions of her neighbour's flat. He described it as a den for the insects and other harmful creatures. You packed your stuff immediately and headed to the house which seemed to offer you a lot of work. The house was indeed lamentable from outside so you asked the permission of the police and entered without the grant of its owner. Appallingly the flat was neat inside and there was no sign of any insect. You wanted to leave but the door was locked this time. Find hidden objects and fit them together to open the door. Good luck!
