Let's Try Once Again

"Duh, when are you going to tell me? When the moon rose high up in the dark sky or the next morning as the sun shines in the clear morning sky?" 

"Hmmm… Of course, I will tell you why I am so curious but not now. Since what we need to do now is find a key to unlock this lock." Ines held the lock in her hand. 

She inspected it and realised the lock had a tiny hole. It was not like the locks that they could find in the regular shops; rather, it had an odd design. There was no visible space where they had to fit the key. Just a minute hole, barely enough for a pin. 

She frowned and continued to check the entire lock. The hole was on the backside. She turned it to the back. 

Her frown got deeper as she saw that hole's size was smaller than what she had originally guessed. 

While Diana watched Ines in pure confusion. She couldn't understand Ines's actions.
