He lightly touched the knob and pushed it a little. "Hmm… it is locked."

He carefully touched a small key hole at its bottom, figuring out which key would fit inside it. The man was now really excited to see what was inside the hidden door. He quickly took out all the keys from the pouch and stuck the biggest key in the key hole. Very gently he turned around the key opening the door. "It opened!"

He pulled it open and realized it was not a door to any room but it was a big sized cupboard. The man frowned a little looking inside it. There were several shelves inside it, which seemed to be unusually clean. Most of the shelves were empty except for the last two ones. There was a small diary on second last shelf and he picked it up, looking at it carefully.

The diary was dated to be at least 26 years from now and he opened the front page reading it. "Oh my Goodness. It is mother's journal."
