How can a person be invisible, this is absurd" Mr. Harris said as they came out of the room.

Andrea and Jade looked at each other with a knowing glare.

"You are right, maybe he hacked the camera so that you cannot find out who did this" Andrea lied not wanting the manager to know the truth.

"Maybe... " Mr. Harris agreed, still dazed with the robbery of the bank.

"Will you excuse us, we have to talk this scenario out and see what we can do" Andrea said to the bank manager.

Mr. Harris nodded and moved ahead. When they were sure that he was gone, they turned and retraced their steps to the vault room.

"My guess is that the thief used the invisible power disc, what do you say," Jade said as they reached the room.

"The thief can't use the invisible power, that is completely wrong," Andrea said explaining to jade.

"What is wrong in using invisible power for doing this, I think this is fabulous," jade said at which Andrea raised her eyebrow.

"What, I  am just saying he is smart, but we are smarter"

Andrea laughed at this "You are right we are smarter than him, but that was not what I meant when I said that the thief could not use invisible power"

"So what did you meant?"

"What I meant was that he could not use that power because there is no invisible power disc" Andrea explained.

"This makes it a lot harder to find out how he did the thefts now"

"Yeah, I agree"

"Let's search around and see if we can find something useful"

Andrea nodded, "You look around here while I take a look inside the vault"

Jade agreed and they started searching their respective places for any traces left by the thief. but, they did not find so much as a fingerprint or a hair for evidence.

Finally resigned they stopped outside the vault door.

"The thief is wise, he had left no evidence," Andrea said.

"So what should we do now?" Jade asked frustrated.

"I don't know, my mind is going blank," Andrea said in an exprasated voice.

"I too Cannot make heads or tails of this, how I wish that our gear could find out any traces of other discs used"

At this Andrea quickly stood up "That's it, you are  brilliant Jade"

Jade's confusion was clearly shown on her face, when Andrea saw this, she shook her head and explained.

"We can use the disc scanner, to see if anyone in the bank still has a disc and the invisible thief is still in the bank or not"

They rushed to the reception area and found the manager there sitting dejected on a chair. They went to him and told him that they have a way of finding the thief "But for this, you have to make this announcement" Andrea said, she told the announcement to the manager.

Mr. Harris in the thought of getting back his money agreed to make the announcement. The announcement was made on his order, everybody gathered at the reception, standing in a row as per the announcement.

Andrea turned on the detector and much to their relief it started beeping.

Andrea started revolving it around and stopped it in the direction where it was making the highest noise.

She went to the person on whom the detector was ringing and an astonished Jade followed her. They were doubtful when they reached the person, for the person was none other than the guard.

The guard too looked confused when they came towards him.

Andrea reached the guard and to everyone's surprise, declared "He is the thief".

Mr. Harris came there.

"Are you out of your head officer, you think my guard is the thief?" He said in an irritated voice.

"Are you sure about this Andrea?" Jade asked.

"Absolutely and I can prove that," Andrea said confidently.

She turned towards the guard "So you're the guard right, What were you doing when the theft happened?" She asked.

"I was outside at my post" he replied.

"Can I know your ID number, if you don't mind"

The guard now looked uncomfortable "its 7045 ma'am" he said.

At this Andrea turned satisfied "As you can see he is the thief" she declared.

Mr. Harris quickly ordered the other guards to catch hold of him.

Andrea again turned towards the guard and took something out of his wrist, then turning to Mr. Harris she said: "We will take it from here".

"Guards take him to the police car outside" she ordered the other guards.

They took him to the car both of them followed.

When the thief was secured in the car, Andrea started the car. After some time they reached their base. Taking the thief to the cell they locked him up.

After this Andrea ordered some coffee for both of them. When the coffee came they took it to the table.

Jade opened their case file and handed it to Andrea. Who began filling it with their recent case.

"Wasn't this a wonderful case?" Andrea asked who had stopped writing to talk a sip of the coffee.

"The case was good" Jade agreed "What I don't understand is how did you figure out that the guard is the thief".

"It was simple, he gave me the wrong ID number"

"How do you know that it was wrong?" Jade asked.

"The ID number he said was wrong because it had four number, but the real ID number for the guards there has eight numbers"

"Ohh,  you are brilliant but I am glad that this is over now"

"True, I am glad too" Andrea replied with a sigh.

"I just hope we have another exciting case soon"
