It was almost 10 pm and Chris Stephen was preparing tea for himself when he heard someone shouting his name. He looked out of the window and saw his friend, Morris. Stephen went down and greeted him. Morris said, "Pardon me, Chris but we need your help in solving a mystery. A very rare and expensive diamond, known as Sky Diamond, was stolen from the diamond shop. Police have no clues who stole them and we need you to help us catch the culprit." Stephen agreed to help and they both went to the diamond shop. There were many policemen guarding the shop. Stephen went inside and looked at the shop. The other diamonds were there but were dislodged from their place. Stephen, wearing a glove, carefully picked a diamond and examined it. He saw that there were no finger prints on the diamond. Stephen announced, "I've deduced that the culprit was wearing gloves when he took out the diamonds." "We also found out that our guard dog, was shot by a gun. But the people living nearby said they didn't heard a single gunshot in any part of the day. We don't know who this person is and how did he enter the shop under such security." Said John Holmes. "Let's look at the guard dog, "said Stephen.
