“Sir, I have an idea. You know, how the killer must be entering and leaving the crime scene.”
The detective cocked his head at Jeff.
Jeff went out of the door and closed door from that side.
“Look now” he said loudly, so that his boss could hear.
Sam could see the latch of the door started moving slowly. He looked on, surprised. The latch moved slowly and the door got locked.
“Sir, did you see that?” Jeff’s voice came from outside.
The latch of the door then started moving from the other side slowly and the latch became unlocked. Sam looked amazed.
Jeff opened the door and came in, hiding something in his hands.
“ How did you do that?” Sam asked, bewildered.
Jeff disclosed a huge magnet from his behind and held it in front of Jeff.
Sam looked at the magnet and then at the latch, which was made up of iron.
“Jeff, for your information, the latches at the crime scene were made up of aluminum” Sam said.
“Oh, it was aluminum. That doesn’t matter; I have got solution for that too” Jeff said, realizing something.
Sam looked at him dubiously.
Jeff removed a stone necklace from his neck and broke it. He collected all of the stones in his one hand and pulled behind a nylon thread. He pocketed the stones in his other hand. Now, he held a nylon thread in his hand.
Sam was looking at him with confusion.
“Now, look at the second trick. Just come with me” Jeff said.
Jeff went to the door and inserted a nylon thread into the latch hole.
He held the nylon thread ends in both hands and said “Please, go out of the door.”
Sam followed his instructions. Jeff also went out of the door, holding the thread ends and closed door from that side.
The door was closed and the thread, which was still in Jeff’s hands, was attached to latch through the miniature slit between the doors. Jeff slowly pulled the nylon thread with both hands. He then released the one end and pulled the thread with his other hand. The complete thread came out, which was now in his hand.
“Now, try to open the door.” Jeff insisted Sam.
Sam pushed the door. The door was latched form inside.
Astonished, Sam stared at him.
“Now I am sure.” Sam said.
“About what?” Jeff asked.
“What you must have been before you joined the police force” Sam said jokingly.
Both of them smiled.
“But tell me one thing’’ Sam asked.
Jeff looked at him quizzically.
“ What if the door is locked with a key from the inside?” Sam asked.
“ Then there must not be any way to open it. Other than...” Jeff didn’t finish his sentence, scared at it’s ludicrousness.
“Other than what?’’ Sam asked.
“ Other than some ghostly powers” Jeff concluded.
