Online Novel - Aghast : Ch-23 Jeff’s trick

Detective Sam was sitting drowned in his thoughts. Jeff, his team member, came into his cabin.
“ Sir I have got an idea, how the killer must be entering and leaving the crime scene.”
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. Detective looked surprisingly. The latch moved slowly and the door got locked.
“ Sir, Did you see that?” Jeff voice came from outside.
The latch of the door then started moving the other side slowly and the latch got unlocked. Detective looked amazed.
Jeff opened the door and came in, hiding behind something in his hand.
“ How did you do that?” Sam asked in surprise.
Jeff disclosed a huge magnet from his behind, held it in front of Jeff.
“ It’s the power of this magnet.” Jeff said.
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 of aluminum.” Sam said ridiculously.
“ Oh, it was aluminum. ... It doesn’t’t matter; I have got solution for that too.” Jeff said realizing something.
Detective Sam looked at him dubiously.
Jeff removed a stone necklace from his neck, broke it. He collected all stones in his one hand and pulled behind a nylon thread holding in other hand. He pocketed the stones in other hand. Now he held a nylon thread in his hand.
Detective Sam was looking at him with confusion.
“Now look the second trick. Just come with me.” Jeff said.
Detective Sam followed him.
Jeff went to the door, inserted a nylon thread in the latch hole.
He held the nylon thread ends in both hands and said, “Please, go out of the door.”
Detective followed his instruction. 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 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. What a surprise! The door was latched form inside.
Astonished Detective looked 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 inside?” Sam asked.
“ Then there must not be any way to open.... other than..” Jeff left the sentence incomplete.
“Other than what?’’ Sam asked.
“ Other than some ghostly powers” Jeff completed his sentence.
