Handcuffed Anthony came out of the warehouse, surrounded by armed police force, for he was not some simple killer, he was a serial killer, who had killed four victims one after the other. Police took Anthony to a car. Detective Sam waited back at the warehouse gate. He seemed to be moved by the incidence.
I need to spend some time alone...
The important task of catching the killer is over...
Therefore it will not make any difference if I don’t accompany him...
I can also do the detailed investigation of the warehouse by waiting back...
He signaled his Partner, “ You go ahead. I’ll catch up with you.”

The car in which Anthony sat started, and darted away. The other cars also started and started to follow Anthony’s car. A big cloud of dust rose. Detective Sam kept looking at the settling dust cloud and the departing cars with gloomy face.

As all the cars left and the atmosphere around became quiet, Detective took a round near the warehouse door. While walking he Looked at the sky, it was pink, the sun was about to rise in few hours. Taking a round he came back to the door and lazily entered the warehouse.

It was still dark in the warehouse. He took a round, looked at the glowing computer monitor. Detective went to the computer and saw the software running on it. He tried to operate the software. Some buttons he pressed at random, a device kept besides the computer started blinking. He held the device; it’s a signal receiver, on which there was display. The display showed the ‘In signal range’ Instruction= ’LEFT’. He kept back the device. He again pressed the button on which ‘Right’ was written. The signal receiver blinked and showed ‘In signal range’ Instruction= ’RIGHT’. He pressed other buttons ‘ATTACK’. The signal receiver blinked and showed “In signal range’ Instruction= ’RIGHT’ He held the device, started observing it carefully. Suddenly he sensed something outside the warehouse. Holding device in his hand he went out.

He came out of the warehouse and looked around.
There is nobody here...
Then what that sound was?...
Might be something else...
As turned to go back in the warehouse, the blinking device in his hand caught his attention. His face went pale and white. The signal receiver showed ‘Out of range’ and Instruction= ’NIL’ He kept on looking at the device with his mouth open. There was crowd of so many doubts in his mind.

Suddenly he sensed something around. A black cat ran in the warehouse. Once he looked at the device and then at the warehouse door through which just now the cat had entered. Slowly he started moving towards the warehouse door. He vigilantly entered the warehouse. While entering the warehouse one question was troubling him.
