Once there was a girl named Mina who had a precious gold coin that she always keep with her, it brought her good luck, where ever she goes she keeps the gold coin with her, But one day she lost it in her office! She was very shocked that her precious lucky coin was missing.

She started to look around the office and the areas she had gone but it turns out she didn't find it. So she started to inquire around the office and in her office she had 8 suspects. 

Her first suspect was samuel because he came in her cabin first.

She started asking questions to samuel that did you open my door, yes samuel said, which drawer asked Mina, the left one said Samuel why asked Mina, Samuel said that he had to check on some important files, then Mina asked did you see something shiny, Nop not a thing, ok Said Mina

Then Mina asked Lilly that did you come to my cabbin, Lilly replied no, did you see any thing shiny asked Mina, I did see a diamond ring and 5 Rs gold coin replied Lilly, But Mina was searching for her lucky gold coin not a 5 Rs Gold coin and left them alone because they were not the one who stole her lucky gold coin.

6 more to go said Mina, then she went to justin's cabin, she found him seated on his chair and saw him printing some documents, she asked him did you come to my cabin asked Mina, Yes because I forgot my phone there when we had the meeting, so I went there to bring my phone so I could print these documents replied justin. Mina did not ask any more questions to him because he gave so much information.
